Was I showing off?

So I was playing super smash bros with a group of friends and I was the only the one winning matches, so I brought attention to that (not in a cocky way, but a curious way) and said "has anyone else won any matches", and my friend who's a complete moron (which is a little unfair to say cause he has ADD) says in an annoyed voice, "why are you showing off"? The other kids in the group were a little dumbfounded and asked my friend "how is he(me) showing off"? And then we just continued playing. So my question is, was calling attention to me winning(at a video game) "showing off"?
