Of course, a true daily gambling will lead a person to addiction day by day and that person will start to behave badly. At one time if a person is constantly gambling then surely he will not think about his daily income and financial position but he will continue to gamble and lose. No one can win regularly by gambling every day, no one is lucky enough to win every day, of course you have to lose when you gamble. Of course there are good and bad days in a man's fortune, when good times will come, he will win bets and get a lot of money, and there will be times when he will lose. So I think if such a person is gambling constantly depending on luck then he may win or lose. Others plan that if they gamble every day, one day or another they will win a good amount of money. But we must keep in mind that daily gambling will lead to addiction and one time he will lose a lot.
First of all, why do you think that gambling every day is an addiction, but not hobby? Not everyone gamble to earn. Why gambling can not be one persons hobby. If a person likes drawing, and he buys paints regularly, and a canvas daily, would we call him addicted to drawing or that he has a hobby or passion?
Secondly, like you have said, there are different days in gambling if we measure it with win or lose. It is never be like gambling for 30 days and loosing every single day. So why then it is "lose a lot" as you say. If a person has daily budget for gambling, can afford that, that isnt "losing a lot", that is "spending". And one day profit can be greater than his daily budget.
I think that such a period of daily games ends someday anyway and any gambler moves on to a different mode of play, for example, first he misses one or two days a week and does not play on these days. Then missed game days become more frequent. But by the way, in the long term, almost all gamblers begin to lose money. And if this also happens so often, if he plays every day, then of course all his close people will scold him and express dissatisfaction.
This also happens because such a player spends his time on an inherently unproductive activity. And from the point of view of his relatives, he could be engaged in more useful household activities and would benefit the family. And if there are children, then it would be better for the player to play ordinary children's games with them.
