It’s a term which can be defined in more than one way. One obvious one is
as the relative frequency of different possible outcomes. I think there
are others.

None of our cryptosystems are provably secure.
One example of provably secure system is the one-time pad.
But it’s not. Where do you get the pad from? Proof of security of the
system relies on proof of the randomness of the pad. Which takes us back
to square one.
