Can you explain the rules of poker and how to determine the winning hand when a player has 2 pairs or 3 of a kind?

In Poker, players aim to make the best hand using a combination of their cards and community cards. Two pairs beats one pair, and three of a kind beats two pairs. To determine the winning hand, compare the ranks of the pairs or three of a kind. If two players have the same hand, the one with the highest-ranking cards wins.
