That is very realistic opinion so that I also agreed with you only very few people are lucky to get rich with the help of gambling, majority of the people are on the other side which belong to looser that is why I also think that is really bad way of thinking when we want to get rich just because of gambling.
Those who born lucky they only become rich in gambling. Rest of all like just depositing their amount to casino owners account. Yes, only limited number of people will get a chance to get rich from gambling. For me how gambling helps means I will not become rich, but I will use this amount to fulfil my daily needs that's it.
It all is a huge advantage and also the Lord has destined him to become rich in gambling, as well as to test our faith in the Lord. If we are not tempted or follow in the footsteps of the person and the Lord will replace the property or profits of the person with the larger profits from it. So, do the gambling for the game and always control myself
