Pot odds are the payout offered by the pot expressed in comparison to the price to call a bet. For example, if there was $100 in the pot and the player had to put in $20, the pot was offering 5-to-1 odds. These odds were then compared to the likelihood the player making the decision would win the hand, either by having the best cards or drawing to the best hand.
