TT is a pocket pair and AKs 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. 0.41% of boards are ties, so the equity of each hand is its win rate plus half of that.

The hand ranking puts TT at 5 and AKs at 8 out of 169 starting hands.
