A bookie, short for bookmaker, is a person or organization that takes bets on sports events and pays out winnings to the bettors if their predictions are correct. Bookies make money by setting odds on sports events and ensuring that they have an edge over the bettors. They also manage the betting sheet, track bets, and collect and pay out winnings. https://aceperhead.com/blog/bookie-101/basketball-betting-software/
