Besides even if someone had a way to make money out of the casinos, a capital of 2k does not allow for a consistent profit of 100 dollars per day, that is a profit of 5% per day, and for what I know depending on the sport and the number of matches a successful sport bettor can at most obtain profits of 50% to 100% per year.
So the expectations the OP has are simply out of place as there is no way anyone can make the profits they are looking for, even if every single factor played on their favor.
In theory you could make $100 a day with gambling, you just have to see it from another perspective.
You can buy a small gambling machine, put it at a bar, and see how people start gambling.
You will probably make more than $100 a day with a setup like that.
You will be making money in gambling, just that you will be on the winning side of the bets.
