I do too and I believe the problem with git is that it's somewhat usable without grasping even these basic concepts - until the day it isn't, as something goes off the beaten path and you just end up getting lost. It also doesn't really nudge you towards understanding as you keep using it; to the contrary - it happily lets you build some suboptimal mental models that are doomed to stop working at some point.

The only way to learn git well right ahead is to sit down and read. It isn't much to learn, but most people just skip this step and go straight to CLI. I can't blame them, I did the same many years ago, so it took me much longer to actually know what I'm doing than it should as well. But the thing is: I didn't know better back then, nobody told me that. Now you (the reader) know, so you have no excuse :)
