In sport bet, we don't need to know very much about football. Even guessing can make us to make profits from gambling. This kind of bets can be easy won with luck of guessing something right.
That's not true. You can't win a lot of bets just by guessing in sports betting, you might win a few but that doesn't work all the time. What if you are choosing the wrong team in 10 bets in a row? You are going to lose all of them because you didn't even have any idea about the teams and their strengths and you have constantly been choosing the weaker side that could never beat the opponent. This method can only work if there are two teams of equal strength and maybe the one you've chosen wins the game.
You can only be able to earn money from sports betting if you have knowledge and experience about the sport you are betting on because you will know the weaknesses and strengths of the teams and their players which will make you able to choose the right team every time, and then you might lose a few matches because of luck but you will win most of them.
