Do I have to start studying chess to improve my rating now?

I hit 1100 in blitz, bullet and rapid and my opponents now are definitely more technically sound than me. I never read, analyze or study any chess other than one video of queen's gambit and the sicilian but I'm beginning to think that I'll have to, to actually get any better. Should I start studying chess or just play as I do?

In short, if you are looking to improve then it is generally best to have a healthy mix of playing and study.

Fair enough, I'll start taking a look at some stuff then. I definitely want to get better, thanks for the advice!
