no they do not, nor did film users need to know how to process their own film.

many people know how to use a computer and some did their own darkroom work, but it is not a requirement to use a camera.

But knowing what can be done in the dark room is an essential part of the skills of a top photographer.

So there are no young top photographers? Only oldies know what can be done in the dark room.

According to your logic, when dark rooms fade into nostalgic memory even more, we will no longer have any more top photographers.

Another example of a trollish, and deliberate twist. I gues you don't understand that darkrooms (one word, btw,) have been replaced with digital darkrooms. Do try to realize that technology advances.
