This is the reason why there are so many online casino because they are into a profitable business. Any gambler that thinks he can use gambling to make $100 daily is only trying to give out his funds to the casino because it will never be possible. In gambling one loss more than he wins which makes it not something that you should think of giving you daily profit but see it as what you do for fun,who knows maybe someday,you will hit the jackpot.
even to get a profit of $1 sometimes it will be very difficult if indeed a few days are not lucky and it all comes back to the luck of each gambler even though betting on sports bets is more predictable but luck is still a factor here because there are always surprises in every game so gamblers who think of gambling as a place to make a profit is very wrong. on the one hand gamblers can never get daily profits from gambling even though they are professional gamblers sometimes they lose because emotion will make them get greedy and lose the entire budget and that will definitely happen.
and related to gambling as entertainment or fun yes it is true that it would be better to bet in that way because only with a healthy mindset betting with a small budget just for fun and who knows hitting the jackpot makes more sense than making gambling as income.
