People who play on XBox.. How do you do it?

Basically what the questions says: here on my computer, I have many shortcuts, I use the mouse, I click on things, I mean there are so many shortcuts and keys to press.

Am I getting it right that playing on XBox is.. Playing with an XBox controller? (serious questions, I have never owned any other console apart from PCs)

Isn't it way more comfortable to play on a computer? Or Did you get used to playing it with controllers

Thanks!
