Nit: given a "reasonable" hash, the collision probability should be
the same for crypto or non-crypto hash (for the same width, for "random"
input).

The special thing about cryptographic hashes is that it is supposed
to be hard to create a thing which hashes to a given value (preimage
attack) and to create two things which hash to the same value (it's
hard to "engineer" a collision). So it's about deliberate engineering,
knowing how the hash function works.
