We can't discuss gambling related to religion here as everyone has a different opinion about this and the cycle will just never end. Let's just put it simply that there's no 100% perfect religion where everyone will follow their respective things to be followed. In most parts of the world, people are exposed to gambling regardless of their religion that's why there's always a chance that these people will do gambling even if it's not allowed in their religion.

Same as how people treat liquors, drugs and other considered sin activities.
