You are right mate, there's always a reason why some die-hard gambling will take loan to gamble, it's either they were very confident on the prediction they came up with by themselves of they were confident on the person that gave them a prediction to bet on. There's a saying that "had I know is the last word of a fool, " It's exactly what some gamblers do but when their bet goes against them, they will start blaming themselves for taking a reckless decision, this is also the reason why some people think of suicide after losing the money they borrow.
It is called being delusional. Conviction should be reserved for reasonable things and where it makes sense, such as your ability to do certain types of skills or sports. People can "convince" themselves anything, such as that they will receive a billion dollars from heaven if they burn up all their money in a pit of fire -- this is the level of delusions that we are talking about here. Such moves, even if they turn out to have favorable results due to statistical variance, should never be praised or even tolerated -- they must be sharply criticized for the foolishness and stupidity that led to it.

Of course that is the better option. Many people who are stupid think that they are smart and that by making choices they can make better outcomes with widely familiar and tested strategies. Obviously that is not going to work and if those people were not stupid they would not even try it. Whatever you think of, there's a 99% chance that someone has already done this before or that many other people have tried it before. Don't try to reinvent the wheel, on average nobody here is smart enough to do that. Stick to the well known strategies and betting approaches.
At the end of the day, everyone just needs to find a strategy or structure (fixed or variable bankroll) that gives them an edge and stick with it. The same strategy that works for person A won't work for person B and anyone who tries to force it on themselves will eventually lose because they won't have their own edge even though they another person's strategy. As for me, I still ex experiment with fixed and variable bet sizes. Variable because I want to go big on winners I have good convictions on and fixed on bets with normal gambling levels.
My point is different, I think you misunderstood in the details. Sure, everyone should try some strategies to find one that works for them -- and you are right that one strategy may not work for some people as it does for others and this can happen for many reasons. However, what I am talking about is the difference between these two things: choosing a strategy and creating a strategy. When exploring strategies, one should not be an idiot to believe that you are a genius that will win against the system and create your own bullshit strategy. Instead, when trying out strategies,
you should pick from the well-established, tested and reputable strategies. There are many.
When people are stupid but they believe that they are smart, they create stuff like martingale which is not a strategy but a fool's adventure towards bankruptcy.
