But programs should compress better :-)

I take that back: of course it will have the same information content.

Encripted files have exactly the same information content of the
original, but usually they do not compress at all.

This is because it is important that your ciphertext is extinguishable
from random data.

Indistinguishable, obviously.  I think it's time I went home.

It's not encrypted in a strong-encryption-method sense, I think [1], but the compression outcome should be similar.
