No. Hash functions can be used outside of symmetric encryption. Which is the wording I used.
In any case, the overall point remains. Short of the one time pad you can’t build a provably flawless scheme.
They can be used outside symmetric encryption, e.g. in signature schemes, but the hashing primitives are part of symmetric cryptography.

Again, I didn’t say symmetric cryptography :)
I think you're making a bit of confusion. hash functions are part of symmetric key cryptography, while asymmetric cryptography is public key cryptography that is very different from hash functions.
