You seem to not be getting that words can have multiple (even if related) meanings. When some science or other discipline takes a common word and defines it really precisely for their purposes, that doesn’t change the definition of the common word for all usages and mandate that all lay people use it only with that discipline’s more precise definition.
But it’s a good definition if you are, say, putting a thing into each indentation. That’s why the two definitions are different.
Right, those wouldn’t be holes.

Better precision leads to better communication.
