I don't think there is anyone on earth that will be glad to disobey what their religion is against.  Let's understand that most people do this for money and we can't change that.  You can call it living a two faced life or having double standards and I will say I do not really care what anyone thinks.  

I am not gambling for money, I do it for entertainment even though it is against my belief but I cannot trade my joy for a religious belief that I do not know so much about.  I hope I don't get bashed for this post but this is only my candid opinion. I have some friends that gamble because they are in need and gambling happens to be a sure way to make money, so you will advise them to stay off? Because of personality?  Who cares about personality anyway?  All that matters is the money and nothing else.
