The ease of adversarial collisions has no relationship to the probability of natural collisions.
It's entirely possible to make a cryptographic hash algorithm that has an exceptionally low probability of natural collisions but where adversarial collisions are trivial.
It's also possible to create a cryptographic hash algorithm where occasional natural collisions are expected, but adversarial collisions require brute force.
If it's that easy to generate a false positive then I believe it will be more common to accidentally have one.
Onge again, extraordinary claims require extraordinary evidence.
