On before now gambling was seen as a dirty habit and was painted black in the society because way back the society believes any gambler have so many bad habits too like doing drugs which most gamblers was mafias not just mafias but rich people .
That was then, but now it has become a cash cow for the government and the entertainment portal of the rich and famous, we can say that gambling now is elevated because of the money generated for the government, and some of its patrons are the rich and famous
So my question now is that can someone use gambling as a means of earning living?
Only the government and the operators can, but for gamblers, they have to rely on luck to make a profit but not something to make a living out of it, others who can make money from gambling are workers and some companies that rely on the gambling industries, like the food caterer and entertainers for physical casinos.
