Can everyone really have a set v/s me?

Cause it sure as the hell feels that way. I've lost 3 tournies at Tilt. 2 of them I had an overpair v/s a set. The 3rd AQs on AJ8Q board. The 2 over pair hands were people calling with no odds v/s me and catching. I lost a big race in the early 50K as well with about 1/2 the field gone. Near the bubble of the 20^3 I'm waiting for someone to flop another set on me here too.
