This and similar concerns come up repeatedly. And many times, they have a couple of common themes. One is that people expect to win all the time in situations where they're solid favorites but far from locks - like two overs, often big aces, vs two unders, which is about a 2:1 situation.

Another is that people think they lose more often than they actually do because the losses are larger and more memorable. Shoving something like AQ or KQ and picking up the blinds is highly forgettable, while getting drawn out on by something like a medium suited connector is far more likely to stick in your head for a while.
