Payouts are what a bettor gets out of what he wagers on any gambling event. These payouts may become positive or negative according to the odds he chooses during a particular sporting event. It is positive when he chooses an underdog and then wins. Meaning, the betting amount may earn 1.5, 3, or even ten times the original betting money. It is negative when one bets on a favorite and wins; however the payout is smaller than the amount that one had bet, say 10, 15 and up to 20 percent less. The smaller the risk, the smaller the payouts is. Most professional gamblers prefer to bet on those who are favored to win. Very few put their money on long shots or the underdog.
