You don't need to learn the JVM (beyond getting it installed) to play Minecraft and you don't need to learn Emacs to run Magit.
Yes there is - `alias vim='emacs -nw'` :)
Seriously though, do grant Lisp serious consideration - Emacs only truly comprehensible through the lens of Lisp. The experience may open your eyes to an amazing, wide world of interesting possibilities - Magit is only one of them. No serious programmer and computer scientist would ever outright dismiss Lisp. I'm not saying that you're categorically will fall in love with it, but you may like it. Then, the question "should I try Emacs" would have a completely different meaning.
Or, if you're into neovim, there's Neogit, which is inspired by magit. And if you're not, there's https://github.com/altsem/gitu
Nowadays I open Emacs exclusively for magit. I only know perhaps less than 5 magit commands, however, even use it for staging changes is such a huge leap and its chunk staging is indispensiable.
