Based on the webpage that Jay provided, where I got my numbers...

Of the 169 starting hands, 89 win more than 50% of the time and 80 win less than 50% of the time. This means that of the top half of hands in terms of equity, four of them will win greater than 50% of the time but you're still correct to fold.

Here's an example:

With 22, there are 86 hands with better equity and 82 hands with worse. If you fold, odds are you will pick up a better hand next time and thats why you should fold 22 on turn 9.
