Luck will always be on the side of those who work or make a living from gambling income, because they will try to master the game and will continue to play to earn income for their needs, and this happens to my close friends and even he has more income than me who has permanent work.
and as long as he enjoys and always earns income from gambling he will continue to play, and only God will change it because it has become his way and plan and there will be a good time to change it at the right time.
That is not how it works

. Do you mean that luck will be picky and will pick those people who make living from gambling income

.
Luck isn't picky if you know, it will be on random people whether making a living from gambling income or not. Maybe it happens to your close friends but don't generalize it and saying that all people will experience what your close friends did

Luck has to do nothing with the mode of earning you are using to make money. We shall understand that even when we are earning money through illegal means, luck can be with us and vice versa. I also support this concept that it showers blessings on random people. There are no tricks or tactics of attracting luck.
