wrong in that part , because all the vices you mentioned are completely to spend money but in gambling there is a chance to gain more though it is smaller percent yet there is far different than those others so addiction in gambling is harder to achieve .
and also you are correct that those are all leading to same thing and that is to lose our life if not managed correctly .
When talking about more opportunities to make money, I would say that it is better to choose trading or investing than gambling, but here it is not a matter of how much profit we can get, but the pleasure and satisfaction that we get when gambling so that addiction is more difficult to stop when a gambler can enjoy these two things.
Gambling has the risks of trading and investing also has risks, but on the other hand, gambling provides its own pleasure and satisfaction that we cannot possibly get from trading or investing, so there are no words to waste money as long as we have what we have.
And from this pleasure and satisfaction, it can be very difficult for someone to stop gambling.
