Yes and they are gamblers who only know or only see gambling in terms of winning opportunities but do not understand as a whole that however losing will always be a part of gambling, therefore as you said there are still quite a lot of gamblers who take such actions in order to recover something that has been lost. This means that they only see gambling in terms of winning opportunities regardless of the situation, on the other hand yes I understand what you mean where they can win but it is very small to get a big win for all the losses they have experienced and that is true.
That's what they should pay more attention to, or that means they should know how the impact will occur when they try to restore something that has been lost and this is also the reason why a gambler must have a correct understanding of the whole of how gambling really is, don't just look at the chances of winning but also look at the risk consequences.
When they don't sees their chances to keeps playing gambling because they already lose much money in gambling, they must stops playing gambling immediately before lose all of the money. That's why when gamblers wants to playing gambling, they must sees and prepares their limits and not trying to break the limits because that can gives a problem to them. They will difficult to wins in the gambling games but they will easily to gets lose in gambling games. They must avoids the big loses and will not bet more, especially if they already lose streak before because that have a chance to loses more and more money.
However, playing gambling needs to be wise so they will not forces themselves to keeps playing gambling. Playing gambling is just to fills our spare time and not for playing gambling too long because we knows the risks and we don't have to gets lose much money. We already see what happens to other people who playing gambling excessively and many of them lose their money and even bankrupt.
