The first hand is a pocket pair; the second is a suited hand. A pair against two higher cards is the classic race: the pair is usually a small favorite or close to even, and each overcard that pairs is a way to take the lead.

That is a slim edge: neither hand is far ahead. 0.68% of boards are ties, so the equity of each hand is its win rate plus half of that.

For context, 55 sits at number 27 of 169 starting hands and QTs at number 34 when each is run against a random hand.
