I think you mean actual wrestling. But I experienced growing up with informal wrestling (like at home on the bed during sleep overs). I was oldest by a decade so nearly a only child from this perspective. But my friends with older brothers would dominate. Even later, when there was a playground fight the kids with older brothers were most victorious. Around puberty I self selected out of all the physical stuff; sports and physical conflict. And I’m pretty athletic. I just went towards sports that were more solo oriented. My decade younger brothers, tough as nails. We still horseplay wrestled and all that. I’ve always attributed to Growing up with a teenage version of me during their younger years before I left home.
