It simply means for you to be able to win a reasonable amount, you just have to be winning to lose a reasonable amount of money too, That's just what I understood from the number 7. Because judging from how slot games works, we know there are certain slot games who have a maximum betting amount of $100, of which we all know it's not possible to win in slot with just a single spin, which means before you could win, you just have to have been willing to play at least 20 spins (i.e $2000) and above consistently to be lucky enough to win a decent amount. So on the contrary, the only advice I can give newbies is to always gamble what they can always afford to lose, and stop believing in such stories, as those are mere speculation that could either work or not. Because It's never certain that betting with maximum amount on Roulette game helps users win.
Yes that is also my main point of view because gambling without having to set a specific fund to gamble would lead to uncontrollable lose as well, so as a gambler it's advisable to have fund you can afford to lose to gamble than following the rules number 7. which i think should not be followed to avoid misleading users who are yet to understand how the gambling works or those who are desperate to double their money would eventually go to increase their bet with the hope they would win in next the round or bet.
I agree with you, when gambling, you should definitely set a specific budget, which will not have any negative financial impact even if you lose, that is, you gamble with what you can afford to lose.
There are some gamblers who, after losing money in gambling, try to make bigger bets to recover the lost money and make more profits, which leads them to even bigger losses.
This is why it is important to have self-control when gambling and never consider gambling as a means of making money, gambling should be seen as just a part of entertainment.
