I get your point about recommendation 3 being a bit harsh. However, let's not forget that for many people, especially those with limited financial means, the stakes can be too high even with small bets. It's like they say, "it's better to be safe than sorry". But at the same time, I also understand the thrill of taking a chance, especially when you're in a tough spot and thinking that a big win could change everything. It's a delicate balance, isn't it?
That’s correct, small money can be big money for those who are not wealthy, which makes the OP’s number 3 recommendation a bit harsh like you have noted, but if we read down to the other statement the op made in that number 3 their was emphasis on trying to use smaller amount to chase big win which is a very common character and practice among some gamblers they use small money to aim at big win which if it’s their lucky day then they win.
That is true the money a rich man will see as a small money may be seen as a big money for a poor man and in gambling one ought to gamble according to there capacity and according to there income. And where most people (gambler) make mistake is using a small amount of money to gamble with the hope of making a huge amount of money I mean this is a very wrong mentality and if they are not careful they will not even see any profit because the chance of them winning will be very hard because they will play plenty odds.
