Implied odds and true odds are important in determining if you are making a bet that has good value. When you decide to bet on sports, it is important to have a grasp on a few things. With this being said, lets look at an example from an NFL game. If you find a bet where the implied probability of an outcome is lower than the true probability, then that is usually considered a good bet to make. The odds that a sportsbook offers you is directly related to the implied probability of that outcome happening.
It is very important to know what payout you are getting on a bet.
