There are some ways to earn money without paicing bets and I would like to talk about some of them.
First and the main one is the affiliate/referal programas, this way by sharing your affiliate link you will get some incom from the users bets, isn't easy to get good affiliate (users who bet a lot) but with one high roller you could make a descent amount.
The second one is the VIP programas, like the one that stake offers, you need to bet to grow your account, but once you have a good VIP level you will get a weekly and monthly prizes, It will be better if you bet that month but even without betting you will get something each week/month.
What you are talking about is not strictly speaking gambling... Gambling is a game based on luck. In general, a game is a special kind of activity. Some people call everyday childhood activities a game. Indeed, children like to play various games. Also, the concept of a game is very closely related to entertainment, fun and ease.
A game does not necessarily have to have an end result, but a game of chance always has a specific result - this is, accordingly, the player's win or loss.
Moreover, the result of a game of chance depends entirely or partially on luck. This is the great appeal of gambling - in essence, it is a duel between a person and fate, luck and chaos.
In addition to gambling, there is also entrepreneurial activity related to the online casino industry. This is an activity aimed at generating income, but of course it cannot be called gambling.
