Of course ther's some luck but I can't quantify it. If you don't get the cards you lose. I'm just a learning player. I played four matches yesterday. I was better than all four players but I went 2-2. I was dominating the first player when my AA got cracked to QJ. He calls the allin and flop came JJx - I'm done. Next hand I get AKs go allin he calls with 33, it holds up match over. Next match I'm severly damaged when my AA allin gets call by 97o. Flop 68T - I'm Done. I crush the next two players in our matches. I don't feel too bad because that's Poker!
