There are a lot of players around the world. Not every games are favorite in all region. Some likes soccer, some maybe esports or some cricket or others.
Which one are you mostly placing your bets on? Besides, do you think gambler don't care which sport it is. I have seen gambler who don't have any fucking idea about cricket but he used to bet on cricket.
my favorite sport that I often bet on is football, I don't really understand other sports because I don't like it. betting on sports that I really like, the chances of winning are very big than betting on sports that I don't like at all.
