Experience in sports betting or any other gambling platform may lead a gambler to some winnings but there is no guarantee because luck is an important factor in gambling. Some gamblers who think differently when they get few consecutive wins. At that moment some expect regular income from gambling at a fixed rate that can be $50 or $100 more or less which is considered great mistake. There is no chance to earn specific money in gambling. When a gambler takes such a target, he can loss his money. Remember that gambling is not a business where some one can get fixed profit.
No one should give an Instance of how this could be achieved because gambling is not what we determine the outcome, but we stand to accept any results that comes in for us at the end as an outcome, this means there's nothing certain about how one can win a bet or not except the results comes out, it may be that OP needed a fix income up to that amount everyday to earn his leaving while gambling

it may looks funny but this may actually be his intentions, but it's something far from reality, a lot of things have to be involved beyond betting alone in gambling.
I also see that way, seems that he would like to resort to his gambling for a possible daily profit. $100 is not bad if you can manage
to win on a regular daily basis, but there's no guarantee that you can do it.
It's more on the side that you may lose $100 or more from your initial bankroll or worse, you can lose your entire bankroll in the hope that you can earn
such an amount.
You need to have a good discipline and a mindset not to fall with aggression to avoid losing your patience together with your whole bankroll.
