The chance of a mismatch is 8.63616855509e-78%
If the hash was an atom then you would have to guess which atom in the observable universe it is. That is how likely a collision will happen.
I have posted numerous neuralhash collisions online already[1] and can generate more on demand. The "chance" is 100% because perceptual hashing schemes do not and cannot achieve cryptographic strength.
