That’s not true in the case of possessives like “my son’s toy.” In fact it’s the opposite because the apostrophe here just denotes that it’s possesive which is the opposite of the it’s vs its example.
You might have learned that it replaces part of the word “his” in “my son his toy” but that’s not the real etymology.

It’s not taking the place of “my son’s”; it’s taking the place of “his”.
