Yes when faith and religion are combined with gambling it can seem tempting to many because they can easily expect to gain something. But religion and faith usually try to show people a path that leads to confidence good decision making and conditional happiness. For this reason the relationship between religion and gambling is usually negative, because it is not conducive to a normal and stable lifestyle for people.
What are you trying to explain, man?
Everybody doesn't even believe in one religion or perhaps in their own religion, there are people who don't even believe in it to have any complication with gambling. This is just the believe of people in their own discipline and to also help others not to be wallow in the side effects of gambling. Fath has nothing to do with ones gambling believes based on their religion or trading.
The way I read the guy shows that he was misusing "faith" in that context. That's why you mistook it for the context of faith with the meaning of strong belief. In religion, they often ask which "faith" you belong to, that's the kind of faith he was referring to but he could have just chosen to write either religion, as combining the two might confuse people. As for doing what our religion guides, it's a choice and I do my best to adhere to mine as a Christian if they are indeed adhere to the teaching of the Holy Bible, and are provable.
