You are using the word "uncountably" incorrectly here.

The integers are countably infinite.

The reals are uncountably infinite.

This does not change the equally meaningful statement that exactly half of the integers are even.
It's meaningful only if you define what you mean

If you mean "the set of all even integers has an asymptotic density of ½", then yes, it's meaningful. Otherwise, not.
