I disagree with your conclusions - it seems to me that since a loose player is in more pots, a loose player will tend to win more pots (but also lose more money chasing).
I think a loose player will win more of the big pots, and more of the small pots. A tight player will win a higher percentage of the pots that they contribute to, but if the other players react to their tight play those pots will often be small.

Most people think that playing tight is better than playing loose. Gamblers who enjoy action probably have a lot more fun playing loose, and there are probably some situations where loose aggressive play works better.

If you play no-limit and wait patiently for nut hands to pay off, then I'd think the OP's winning pattern would be pretty normal. I think it would be more unusual in limit games.
