Aliases don't make git easier to understand, they make one specific git command require typing fewer characters to run.

I am not against making aliases, but just saying, if you don't have an understanding of the commands they run, you'll still one day be in a state you don't know how to fix, and THAT is when people "lose their code" etc.

You use git every day, it's worth learning and understanding. You don't need to be a pro, but you need to be good enough.
