My guess is that a bunch of startups that have gone on to do well and were rejected aren't broadcasting that around. Too many other priorities to deal with when things are succeeding and no reason to create any negative feelings about being rejected by YC.
Just think about this. Every successful startup was rejected by some VC. It is par for the course and not really a big deal if you are winning.
