You need money in your life, so you need to allocate your efforts in such a way that money flows from every source. Business or job is a source of money, but if you keep gambling as a priority among the sources of income, then it will lead to bad consequences.
The place where we make the most mistakes is that we want to win regularly in gambling. We continue to play for a long time to earn money because the possibility of winning increases but continuous playing makes you greedy and addicted and the amount of losses increases. Just as you need sleep after a busy day to properly carry out the next day's tasks in the same way after a win in gambling, you should take a break to get another win.
Your statements point to huge shortcoming of using gambling as source of income. Greatest error people commit is attempting to win everytime. Nonstop play is too greedy and addictive, and it will result to more losses. As you would need to rest after busy day, you should get rest after victory at gambling. This assists you in keeping yourself in check and not become blind in your frenzied rush. Idea here is that although jobs and businesses are best sources of getting money, gambling, being a bet, is very risky taking way that can bring in very unfavorable consequences in end since it is not calculated on skills but matter of luck.
