When someone consider that they need to schedule their time for gambling as well then they are some kind of addiction to it, no one should ever make it as daily habit
Did you read Roidz's comment above? I suspect you just reply without reading.

He said that he only gambles on holiday. It means he doesn't gamble every day. So, you cannot judge what he did as a daily habit.
Do you still assume it is an addict?

Make a schedule for your gambling isn't a kind of addiction. Instead, it is the way to avoid addiction. You should know what is the difference between addiction and discipline. Once you become an addict, you will play at any time, without limitation.
I will say it's also an addiction when someone thinks that it is must-add gambling as well into their schedule, probably the earliest stage if you ask me. gambling with time limitation is a kind of discipline where there is no disagreement but my argument is when someone considers that gambling is also a must thing in there to do list for the holidays or any day then it should be avoided though.
