It's not just the number, but how often you dive.
A 100 dives over 5 years does not a good diver make.
It could. Depends on the diver and what one calls good. I do not practice trim or a lot of other things. Only thing I practice are certain safety things like shooting an SMB. I average 30ish dives a year. Some salt and some fresh. I am decent on air and do not kick up the bottom. I am a good buddy and usually can navigate. I am relaxed in the water and enjoy my dives. Play with some fish ID and casual photography. No idea if I am a good diver nor do I care if others think I am a good diver, but folks who buddy with me are usually happy to do so a second and third time.
