Poker outs are any upcoming community cards that can help you form the winning hand. For example, if you have an inside straight draw aka gutshot with KQ on the flop of T95, you would make the nut straight with any Jack. If your opponent holds a pair of Aces, you have four outs to outdraw him. If he had Ace-Ten instead, your outs would increase to ten (4 Jacks, 3 Kings & 3 Queens).
