hmmm I have small hands and short fingers, so I don't have much of a
grip when it comes to larger bottle caps or even jars, for that matter.
Do you think size of hands has anything to do with it?

For large diameter, sure. But, that "problem" would exist from
adolescence, etc.

For *small* diameter, though, small hands shouldn't pose a problem.
Indeed, larger hands can get in the way for smaller diameters
(forcing the user to use fingertips instead of the length of
the finger)

I had a similar problem with my small hands and short fingers when I
played guitar.
