If that were correct, there was probably no contradiction. At least it
was not as easy to see. But it is not correct. We have another measure
for countability, namely: every subset of a countable set is
countable.

Matheologians like to cheat their audience by the proof that a list of
all meaningful definitions cannot be given. "Meaningful definition"
can not even be defined. But who cares? The set of all finite words is
countable. The set of all meaningful definitions is a proper subset.
Hence it is countable too.
