By definition, isdecimal() ⊆ isdigit() ⊆ isnumeric(). That is, if a string is decimal, then it'll also be digit and numeric.
Therefore, given a string s and test it with those three methods, there'll only be 4 types of results.

It's mostly about unicode classifications. Here's some examples to show discrepancies:
>>> def spam(s):
... for attr in 'isnumeric', 'isdecimal', 'isdigit':
... print(attr, getattr(s, attr)())
...
>>> spam('½')
isnumeric True
isdecimal False
isdigit False
>>> spam('³')
isnumeric True
isdecimal False
isdigit True
Specific behaviour is in the official docs here.
Script to find all of them:
import sys
import unicodedata
from collections import defaultdict
d = defaultdict(list)
for i in range(sys.maxunicode + 1):
s = chr(i)
t = s.isnumeric(), s.isdecimal(), s.isdigit()
if len(set(t)) == 2:
try:
name = unicodedata.name(s)
except ValueError:
name = f'codepoint{i}'
print(s, name)
d[t].append(s)

There are differences, but they're somewhat rare*. It mainly crops up with various unicode characters, such as 2:
>>> c = '\u00B2'
>>> c.isdecimal()
False
>>> c.isdigit()
True
You can also go further down the careful-unicode-distinction rabbit hole with the isnumeric method:
>>> c = '\u00BD' # ½
>>> c.isdecimal()
False
>>> c.isdigit()
False
>>> c.isnumeric()
True
*At least, I've never encountered production code that needs to distinguish between strings that contain different types of these exceptional situations, but surely use cases exist somewhere.

Lets see some examples:
str.isdecimal() (Only Decimal Numbers)
Is 34 a decimal number? --> Yes
print("34".isdecimal()) #True
Is superscript 2 a decimal number? --> No
print("\u00B2")
print("\u00B2".isdecimal()) #False
str.isdigit() (Decimals, Subscripts, Superscripts)
Is 34 a digit? --> Yes
print("34".isdigit()) #True
Is superscript 2 a digit? --> Yes
print("\u00B2")
print("\u00B2".isdigit()) #True
str.isnumeric() (Decimals, Subscripts, Superscripts, Vulgar Fractions, Roman Numerals, Currency Numerators)
Is 34 a numeric number? --> Yes
print("34".isnumeric()) #True
Is superscript 2 a numeric number? --> Yes
print("\u00B2")
print("\u00B2".isnumeric()) #True
Is Vulgar Fraction one Quarter numeric number? -->Yes
print("\u00BC")

The Python 3 documentation is a little clearer than the Python 2 docs:
str.isdigit()
[...] Digits include decimal characters and digits that need special handling, such as the compatibility superscript digits. Formally, a digit is a character that has the property value Numeric_Type=Digit or Numeric_Type=Decimal.
str.isnumeric()
Numeric characters include digit characters, and all characters that have the Unicode numeric value property, e.g. U+2155, VULGAR FRACTION ONE FIFTH. Formally, numeric characters are those with the property value Numeric_Type=Digit, Numeric_Type=Decimal or Numeric_Type=Numeric.
So isnumeric() tests additionally for Numeric_Type=Numeric. Quoting from a historic proposal for official numeric type definitions:
Numeric_Type=Decimal
Characters used in a positional decimal systems, which standard base-10 radix systems with contiguous digits 0..9, and are most-significant-digit first (backingstore order). These are coextensive by definition with General_Category=Decimal_Number.Numeric_Type=Digit Variants of positional decimal characters (Numeric_Type=Decimal) or sequences thereof. These include super/subscripts, enclosed, or decorated by the addition of characters such as parentheses, dots, or commas.
Numeric_Type=Numeric Characters with numeric value, but that are neither Decimal nor Digit.
So any character that is numeric, but not decimal or a variation thereof. Think fractions, roman numerals, glyphs that combine digits, and any numbering system that is not decimal-based.
That includes:
>>> import unicodedata
>>> for codepoint in range(2**16):
... chr = unichr(codepoint)
... if chr.isnumeric() and not chr.isdigit():
... print u'{:04x}: {} ({})'.format(codepoint, chr, unicodedata.name(chr, 'UNNAMED'))
...
00bc: ¼ (VULGAR FRACTION ONE QUARTER)
00bd: ½ (VULGAR FRACTION ONE HALF)

However, the distinction between Numeric_Type=Digit and Numeric_Type=Numeric is no longer considered useful, and Numeric_Type=Digit is no longer used for new characters since Unicode 6.3.0. Quoting Unicode Standard Annex #44:
Starting with Unicode 6.3.0, no newly encoded numeric characters will be given Numeric_Type=Digit, nor will existing characters with Numeric_Type=Numeric be changed to Numeric_Type=Digit. The distinction between those two types is not considered useful.
Thus, 🄌 (DINGBAT NEGATIVE CIRCLED SANS-SERIF DIGIT ZERO) and other characters that once would have been assigned Numeric_Type=Digit have instead been assigned Numeric_Type=Numeric, and they report False for isdigit:
>>> '🄌'.isdigit()
False
2 of 5
5
unicode.isnumeric()
Return True if there are only numeric characters in S, False otherwise. Numeric characters include digit characters, and all characters that have the Unicode numeric value property, e.g. U+2155, VULGAR FRACTION ONE FIFTH.
str.isdigit()
Return true if all characters in the string are digits and there is at least one character, false otherwise.
For 8-bit strings, this method is locale-dependent.
