It is impossible to play for fun when you play every day. When you play every day, it becomes part of the process, you cannot live without it, and accordingly, there are no limits in such games, and there is a direct dependence on the game itself. This will not end well, and sooner or later, even if you are lucky now, you will still lose everything.
It will depend on the budget of someone and his gambling style. Sure, most people probably won't gamble daily, it can spend bigger funds. Anyway, I don't know how often OP gambles in a week. I just guess that he may gamble daily. The point is I suggest him to stick with his plan and don't try break his limits. I believe every gambler should have a limit on his gambling budget or time to spend. 
I'm not arguing, it just seems strange when a person gambles every day and thinks they have everything under control. Daily gambling in itself is not control, it's much greater risk. But overall, you're right, if he sticks to his plan and doesn't go beyond it, and at the same time is confident that he has everything under control, then that's his business, maybe he really does have everything under control.
