The majority that produce _falls_, yes, but not _finds_, I think. That
is, your typical find (either a single individual or several pieces)
probably didn't come from a spectacular meteor event. Of course, finds
in large strewn fields are a different matter.

Atmospheric entry models demonstrate that it's not difficult for a small
body to drop a few rocks on the ground without ever depositing the sort
of energy into the atmosphere we associate with bright fireballs lasting
several seconds and producing audible acoustics at ground level.
