Of course, this rarely happens, more precisely depending on luck. However, sports betting certainly requires prior research on the team we will choose, we can't just place crazy bets on any team we will bet on. Unless both teams are equally strong, it is possible to place a big bet because the winning result depends entirely on luck.
For sure there is more to do in terms of sports betting; even when we are to make those crazy bets, it's not like it's a game based on RNG. This one requires your research to determine which team you are to pick against each other and pick that one with crazy odds and leave the rest for your luck to determine how the outcome will look.
