In poker, when your chance of winning the pot is mathematically more than your opponent, you will be a favorite. Otherwise when you have a hand that does not have the better chance of winning, you will be an underdog. For example in a heads-up Texas hold'em poker match, if you are holding and your opponent has , you will statistically win nearly 60% of the times and lose 40% of the times, so you are a 60:40 or 1.5:1 favourite to win and your opponent is an underdog.
Sometimes, you will be in a situation where neither you nor your opponent is an underdog because you will both win nearly half the time. For example, in the confrontation of AK-suited versus pocket deuces (22) in Texas hold'em poker, each player has roughly a 50% chance of winning. This situation is called a coin flip.
Of course, being the favourite or underdog doesn't necessarily mean that you will win or lose the hand but it is always good to know the math behind your action.
