No, Emacs should be configured to your liking. The default Emacs keybindings (especially the more complex ones for common things) suck.

That said, you're still using Vim keybindings within Emacs and for some operations that Vim has no equivalent for you will need some Emacs knowledge. Also, some thing that Vim does have an equivalent for are easier to do in Emacs.

You cannot step into Emacs + evil-mode thinking you will never need to know anything else. You would be well advised to learn some Emacs basics and then help functionality.

For day-to-day operations like buffer editing you'll be able to use you Vim muscle memory.
