It's a text editor. You can work when you know enough do common textual operations to add remove and modify text, search through existing text, jump around to different files in the project, and run whatever constitutes a build.
More sophisticated ide like features normally constitute reading the documentation for a particular project like cider for clojure.
I have no idea why you consider 4 and 5 fictitious. One can read the entirely of mastering emacs and the cider docs in a reasonable period of time for example.

It is one thing to know enough and quite other to be proficient in using them effectively. With the horrible and unintuitive default keybindings it takes even longer to develop muscle memory.

Yes one can in theory. But again if everybody could become proficient in something just by reading manuals then we could shut down our expensive schools and colleges and any sort of practical training. Also, everyone could then program in `ed` or TECO.
Curious, have you actually met any other person who's not an emacs user in real life, like ever? Here's an experiment, go to any decent software company and ask 5 new hires who've never used Emacs, give them the manual and see how long it takes them to actually do something significant? Then give them VSCode and compare notes.
Did you mean to ask if I'd ever met an Emacs user? I'm pretty sure we both pass people who haven't heard of any text editor or IDE all the time.
I'm not likely to meet many Emacs users regularly as I don't work in tech I'm just interested in it. I've met Emacs and vim users at a clojure meet up but that isn't exactly shocking.
