In gambling, profit is not guaranteed hence it is not a good idea to set an amount to earn daily. Often, gamblers are losing their money than winning, that's why it's not advisable to treat gambling as your source to earn money.
Yes, even as we all know, that the probability of winning is smaller than the ratio of losing. so, as you say. that to make a consistent income in gambling, is not a good idea. except, if the OP has expertise in a particular area of gambling. even then, there are no guarantees at all. maybe, rarely gamblers realize. that in every gamble, defeat is always close for gamblers. it's just that, here, how do we use experience, insight and knowledge, especially responsibility. so, every gambling session that we play is not done carelessly. nothing else, so that we avoid defeat. and importantly, always involves responsibility.
You can try different strategies but none of them are proven to be effective in the long run. Anyway, you mentioned that you tried it before (earning daily through gambling), so what games are you actually playing? If you experienced it already then you know better if it's really possible or just a desire. Nevertheless, gamble responsibly by using only the money that you can live without.
As far as my experience goes, there is no single strategy that is truly effective in gambling, especially if it is not accompanied by luck. however OP has his money, if he doesn't use it wisely there in gambling. which in the end, OP will lose all the money he has. well, as you also said, that the type of game that is played is very important. if the game is purely a game of luck, then don't expect to make consistent profits per day. because, it seems very unlikely. however, if the OP is interested in betting on another type, say sports. OP can have a big chance of winning. it's just that, it takes knowledge, experience, as well as insight, and even then it's not easy. so, there are no other words other than what we agree on, that make gambling part of a fun hobby but the conditions are accompanied by responsibility.
