Test player 4 (Red Dead Redemption 2)

Hello! Do not understand what is required of me in this trial. So, the task: beat another player to the poker in every region. The explanation is written down: players are considered losers in poker when they have no chips. As I understand this test: poker playing not alone, and 4-6 people, but you want to defeat single-player, therefore one was left of the chips he loses, and who is left wins, which is what happened when I played in Valentine. Comrade went to zero and left the table as losers, therefore I won, but the question remains what to do with other players? I have to be alone? In short I'm confused. Help pliz who passed it. Explain not reasonable that, Yes?
