Each side holds one of the pocket pairs: 99 and 33. A pair against a smaller pair is the classic crush: the smaller pair needs one of its two remaining cards to make a set.

A gap this wide means 33 is in trouble before the flop and has few good runouts. A split pot comes up on 0.73% of boards, so the wins and the equity differ by half of that.

By strength against a random hand, 99 holds place 6 of 169 and 33 holds place 66.
