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.
I don't think so because luck will not come to all the people who work or make a living from gambling.
Luck will come only at the right time and in the right place, and of course, luck will come to the right person too.
Even if that person tries to master the game, it doesn't mean the luck will come to him because it's not like that the luck works.
The luck will come if you deserve to get the luck and you are the right person to get those luck.
Many gamblers are trying to get their luck, but unfortunately, the luck will not appear to them, so that makes them lose the money.
Maybe your friend has better luck than the other friends so he can win the game.
But I don't think he can always win the games because luck will not always come to him.
Well, even if the player is extremely lucky, and luck comes o him all the time, he will still lose in the long run because the house edge will eat the bets soon. Math always win in game of math vs luck xD
