Gambling, in my opinion, shouldn't be seen as an activity to gain millions, even in the long term. It should be a hobby of sorts, where you spend a sum that's okay for you to have a good time and thrill from the process itself. OP can try Sports bets, sure, but they are two different beasts - one can be more analyzed and debunked by those invested in it, other - is a simpler counterpart, but that's the beauty of them, two of the activities are good in their own ways.
