Well, if you don't want to get better at chess, that is perfectly alright. You can play this game only to have fun! Even if that means always being on the same level! I want to improve also because I think I will have more fun that way.
That said, if you really want to improve, will only playing be enough? I think only to a point. You might get more experience, which will manifest, I think, especially in making less simple mistakes (important), but even this is not a guarantee- some people played AND studied for years and are still making many simple blunders.
But imagine you only played against GMs, and never took time to study, let's say, in the form of analyzing your games after playing them. I think that you would get startegically outplayed in many games, and you wouldn't really know why. So you wouldn't ever learn the lessons from these games.
Maybe you should keep on doing what you have been doing- for a time- and then decide if you want to study or not! Peace!
