QQ is a pocket pair and QJo is an offsuit hand. One hand holds a card of the same rank as the pair, which removes a card the pair needs and makes the pair a bigger favorite.

That is a heavy lead: QJo needs the board to help it on most runouts and still falls behind far more often than not. Ties are part of the picture: 1.64% of boards end in a split pot, and each side counts that as half a win.

The hand ranking puts QQ at 3 and QJo at 39 out of 169 starting hands.
