I feel weird, can someone tell me what's wrong

I won my first ever tournament, bumped down a weight class. (144-138 and my varsity record is 9-3 this season) I was dominant the entire time all of my wins were pins in the 1st period besides one I guy i tech falled because I wanted to. I'm used to getting beat up and being the loser. I was bullied most of my time in middle school then I started wrestling my freshman year. I never would've made friends if I didn't. I'm in my junior year now and im a winner which is something I'm not used to. It feels weird to me, I'm not supposed to be this good. It's not like the competition was bad, I beat the varsity starter for the 13th ranked school. I know I should be fine with this but it kinda feels off as I'm not supposed to be a winner.
