What is the significance of a Texas Holdem side pot in a poker game?

In a Poker game like Texas Holdem, a side pot is created when one or more players go all-in with different amounts of chips. The significance of a side pot is that it allows players who have more chips to continue betting and potentially win more money, even if the all-in players cannot participate in further betting. This adds complexity and strategy to the game, as players must consider their chip stack and potential winnings from both the main pot and any side pots.
