Hmmm. Well, I play this game (Clash Royale) on my phone. Sometimes I'm really good and other times really bad. And I don't always realize why. But you do tilt sometimes, and not always in a way you can see yourself. It's the same with typing I feel, some days have great flow and others are awkward. Piano playing, the same.
My best advice would be to enjoy yourself. Relax the demands, type and have a good time. Speed and accuracy will come in time, and for now just have fun.
