Of course, I'm not. Maybe we differ on the definition of stable because what I understand about stability in a gambling perspective is not winning daily or weekly, but at least you'll end up winning in the long run. Just like a casino, they don't win on a daily basis, but they win in the long run. I know it sounds impossible for most of us, but there are people I follow doing sports betting, which they call pros, and they are showing how profitable they are.
Sometimes they will have a losing streak, but since they have a decent bankroll to withstand that kind of situation, they were able to recover until, in the long run, they will still end up profitable. If you live within your means, I think you can survive with your gambling income, considering you are profitable.
Well, you're right with your submission but if you observe closely in your first paragraph, your points justify it more why gambling can not be a reliable means of income. Let look at it from this perspective, perhaps you will get the angle I am talking from. Let assume you have no any other sources of income to survive aside gambling and you have $1k that you intend to gamble with in order to sustain yourself. Remember you are going to feed, do other things and still gamble from this money. Luckily, you manage to increase the amount to 5k within a month while you continue to feed from and all of a sudden, gambling decides to show you it's negative side and you slide into losing streak for complete a month. In this month, you are feeding from the money and still losing some part to gambling which left you with less $100. At this point, I know you'll feel devastated and confused on whether to continue gambling with the remaining money or to buy more foods. If you choose gambling, there's a possibility you will lose it all and if you buy foods, what will happen if it finished? You'll eventually agree that gambling is not a stable source of income. I know this explanation is not perfect but I hope you grab my point. The point is no matter how profitable gambling is, it can not sustain one for long. Hope we are not deviating from the main topic of discussion, let end it here.
