One side is an offsuit hand, the other is a pocket pair. 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.

This is close to even money, with 44 a little ahead. 0.48% of boards are ties, so the equity of each hand is its win rate plus half of that.

For context, AJo sits at number 15 of 169 starting hands and 44 at number 48 when each is run against a random hand.
