I think margin of victory does matter in gambling affairs, particularly when betting on sports such as football, basketball, and hockey. When betting on such events, bookmakers offer point spreads, which means that bettors are not just wagering on a team to win the game but also to "cover" the spread.For example, if a bookmaker offers a point spread of -10 for a favorite team and +10 for the underdog team, then those who bet on the favorite team will win their bet only if their team wins the game by more than ten points. Similarly, those who bet on the underdog team will win their bet if their team wins the game or loses by less than ten points
