There's nothing wrong with any of these things. Every respected sportsbook pays winning customers. It doesn't matter if GekkeBelg did steamchase or used oddscreen like Spankodds. The whole point of being a sports bettor is to take advantage of the odds, it's literally the only way you can win.
That’s the thing. You cannot and should not make gambling your job. It is the only way you can win means it is the only way the casinos lose money. Casinos want to make money in the long run and you want the same thing. Both of you cannot coexist. One of you should stop and I can assure you it won’t be the casinos.
Take that any way you like.
You simply cannot win in the long run. Even if you beat math, you’ll lose to ToS. There is a reason why the casinos ban stuff like arbitrage betting, ev betting etc. they make them lose money.
You can get lucky and win every once in a while.
The casinos are always lucky in the grand scheme of things. Luck their job.
