Here an offsuit hand (AJo) meets a suited hand (53s). Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits.

That is a modest edge, the kind that shows up over many hands and is easy to miss in one. 0.51% of boards are ties, so the equity of each hand is its win rate plus half of that.

AJo ranks number 15 of 169 starting hands, and 53s ranks number 146, by equity against a random hand.
