not all types of gambling can be profitable in the long term but there are some like poker or sports betting where you need strategy and if you have a really good one you can profit
I would argue sports gambling is probably the hardest thing in the world to have an advantage at. Unless of course you're playing in the game itself which is illegal.
The reason it is a lot harder, is because you have professionals picking against you.
It is wrong. Sport betting is the most profitable gambling games which many people already acknowledge it because you just need to gather some information of some particular match so you can make sure your bet will win or not plus the percentage of winning in sport betting is higher than other gambling games. And there is some free or premium pick for you to choose, but if you dont believe them just make your own
Sports betting also depends on luck to win, not all of our prediction and analysis will come true. There are a lot of example of sports bettor lose big in a very low odds which is likely will be a 99% win bet.
