If you learn to be a full-stack developer, does that cover a lot of ground within software developement?

Might be a silly question but does learning full-stack give you good grounding on most things software dev? I know there’s always something to learn and you’ll never learn everything but I just mean does it cover most of not all areas and gives a good foundation and anything else you learn won’t exactly be “new” because you would have come across the idea or concept when you are learning to be a full-stack developer?
