These are perceptual hashes though.

What if you take a picture of your naked baby in the bathtub or your child on the beach, and the picture is very similar to a known CSAM picture with a hash in the database, enough to pass the distance threshold they're using?

The picture would be sent for screening, the Apple screener would indeed say that's a naked baby/child, and soon enough you've got the FBI (or whatever is the equivalent in your country) knocking on your door and arresting you for pedophilia.
