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.
there are 2 types of gambler , the one who bets for enjoyment and of course to win while there are others that only bets to win and care nothing about which game he will be betting and which team he will be choosing .
this is how i can describe gamblers according to my own experience .
Nowadays i mostly bets in Sports in Footbal(american football actually) and sometimes in Boxing specially when big boxers tried to defend their title/belt.
