You can have something that when observed appears to be uniformly random but can be transformed into something that is not. Consider a Hadamard transform applied to |+>.

Or decryption?

Possibly - though decryption relies on other information held elsewhere (the keys), so I imagine within physics it then turns into a hidden variable problem.

I feel that the operative difference is between “being” and “seeming” uniformly random.
