I am sure that everyone here will say that the intention of this idea is good, because after all helping each other is a good thing to do, but what I question here is the involvement with gambling, meaning whether from the beginning they really believed that they would be able to collect money from gambling and then donate it to people in need? Honestly, I am not sure about the success of that, although yes, victory is part of the end of the game besides defeat, but what I am worried about here is that in the long term they are far from luck which actually makes their capital disappear without a return. So in my opinion, what is more effective is not to involve gambling as an intermediary to solve various problems that are tied to finances, maybe there are some other options.
If you think about it, for example, someone who has a role as a bookie opens gambling and the proceeds will be intended to be donated, actually this is good because there is a good side that will be done, but you are right in saying that it seems better not to involve gambling, if you really want to get donations to donate, maybe you can use other methods such as holding entertainment or other things that make more sense because I myself think it doesn't make sense to involve gambling.
Actually, for a profit or raising money by gambling, I think it can be done because there will definitely be benefits that can be obtained or money collected, it's just that it's not ethical in my opinion to raise funds to donate by gambling, but if it's already done, it's best to continue until the funds are collected and donated.
