You did not make a mistake. Others did.

In terms of code factorization, polymorphism simply means
"factorization of a name". Same name, different code. The actual code
used is decided by some underlying/implicit mechanism.

Anything that fits the criterion "same name, different code" can be
called polymorphism. It can be applied to data or functions/methods
alike.

"Polymorphism" itself means several things. In a sense, the term
itself is polymorhic: same word, several meanings. The precise meaning
depends on context. If you understand this last part, you understand
polymorphism. :)
