Firstly, if you just say and relate to various activities which according to all religious teachings are prohibited and haram then it is clear that many of these prohibitions are violated and are not really cared about.
Not only gambling, but consuming alcoholic drinks, free sex, and narcotics are all prohibited for all existing religions because religion teaches virtue and also the philosophy of living with love for God and carrying out the various recommended religions.
But in reality, many people violate all of this out of mere satisfaction and of course this is mistake if it is judged using religious teachings and regulations prohibiting religious people.
We can only remain good people by not harming other people, even if we do some prohibitions, but if it doesn't harm other people then just do it because whatever the consequences, only we ourselves will accept it.
If you really think it all mistake that needs to be fixed then leave everything behind, never try again to do anything that is clearly prohibited.
We live in modern times and when many religious prohibitions are violated it has become habit that cannot be avoided.
In gambling, we ourselves decide to start and if we can't accept it then just do what we think is right.
If we pay attention, there are many activities carried out by humans that are prohibited by religion but still do them for many reasons. It's the choice of each person who does it, and it seems like they already know it, but they don't stop doing it. We also can't force them to stop doing it because it is their choice to keep doing it, and they like it, so they still do it. Yes, we can only be good people who do not harm others or disturb others. As long as we don't harm each other, everything will be fine, and if a problem arises later because of what each of us does, it will be our responsibility, so we must be able to find a solution to solve the problem. Maybe later, they will realize what they did was wrong and try to stop what they thought was wrong. It takes awareness from them to know that it is wrong and just let them do what they want to do.
We admit that many religious prohibitions have been violated. We must reduce violating these prohibitions by being good people towards others. Later, we will be given the awareness to admit that what we did was wrong and try to change it.
