If you're winning consistently, then yes you're probably doing something right. The thing is, the guys are right - 1000 tournaments in MTT's really is a very, very, very small sample size. The best way to find out if you would be a consistent winner would be to post a few tournament hand histories of which you won that way the more experienced MTT players will be able to tell you if you have luck boxed your way a few times or if you're playing correctly.
