Well I see that as a weak and negative mindset to gambling. If you are gambling because you have meagre resources and want to earn a living as a gambler, it is a very wrong decision as far as I am concerned because it will end up ruining the person's financial life and well-being. People who have small economy should do less of fun things to make money, since gambling is also a way of catching fun. They should diversify in different businesses to scale up their business opportunities.
But of course a lot of people caught up in this situation, gambling with the intention of making more money. I will say that is wrong and they should have instead think of creative ideas that can even create gambling platform ls or games like you.
Example: Streamer, Poker Profesional. As long you can control and manage your self, these industry have some potential. Especially on (Streamer) the money flow is really big as you can see the contract between Stake - Influencer
It's really rolling.
Or better still, people can pay more attention into creating the gambling platforms with the intention of making more money through it. Like those creating casino games out there, many of us can come up with much creative platforms and betting games that will interest gamblers thereby making a living from it.
