I am using git as a version control system via Tortoise GIT which does a great job of exposing the minimum required functionality of git (maybe a bit more than minimum) and it is only when something goes wrong or I need advanced features that I have to fall back on git command line. So 99.99% of the time I use 10% of git functionality. Even if I did learn all of git (and I doubt there are many people that can make that claim), I would probably forget most of it by the next time I needed to use a particular feature. The main thing that should be explained at the start of any git related tutorial is how git handles the full workflow (from remote to local to work copy and back) because that is one thing that is missing but once you know it the rest becomes easy to understand.
