Emacs has user friendly command names, functions in Emacs have a full command name. Can you guess what "comment-region" does? That's right it comments out the currently selected region. Or "switch-to-buffer"? That's right, it's used to switch buffers. Obviously if you use these things regularly typing all that gets tedious so you can use keyboard shortcuts like C-x-b to switch buffers instead. Sometimes these have relation to the command they call but sometimes they don't, but neither does something like Ctrl-Z (What does Z have to do with undo?). Emacs doesn't have autocomplete built in but it does have tab completion and if you press tab it will show you possible functions that start with what you typed if there is more than 1 option available. I think most of the trouble people have with Emacs is that it doesn't use standard terminology or conventions mainly do to its age. There is nothing more discoverable about Ctrl-Z vs. Ctrl-/ other than that Ctrl-Z became the defacto standard. If you took two novice computer users that have never used a computer in their life I think they would have just as much trouble with VS code as Emacs.
