People are much more likely to remember the moments when they were unlucky than the moments when they were lucky.
In addition its more painfull to lose a hand, when it bust you from the tournament, than when it just reduce your stack, because you had the opponent covered. So losing as the small stack is remembered more than losing as the big stack. In addition like others have said, having a large stack in a tournament actually allow you to open up your range and play more hands especially at the bubble and the final table. The best players in the world do that as well.
And when you play a wide range, then you will more often be in a situation, where you are behind but have
equity, and then you will put more bad beats on other players. A simple example is, when it folds to you in SB, you have 50BB, and BB is a mid stack with 13BB. Then it can be GTO strategy to jam any two cards to pressure the mid stack, and when he occationally find a call with a hand like AK, your 72 will have equity and bust him like 1 out of 3 times.
This does not mean, you played poorly, or that the RNG reward poor play, or that the RNG is set up to let the big stack win. Its just simple math, but people get emotional about it and completely ignore the 2 out of 3 times, that AK hold and dubble up against 72. Often this mentally is combined with a lack of poker skills, where people simply dont know, that the opponent did, exactly what he was supposed to, by jamming his 72 into their much shorter stack.
