This is one of the reasons I hate cash out. This is also one of the reasons I do not like to watch any of the matches or their live scores until the matches ended. I have staked on a match before that the goal that made me won the game was scored in the 5 minutes extra time given and it was less than 1 minutes 30 seconds to the end of the match. Also can someone lose within that short minute. As for me, even if I am losing, I do not cash out. The money that is always offered for cash out is not always favoring.
Gambling can't be predicted, you can't really tell when to win or when to lose that is why it is good whenever one wants to play gamble it is important to play with the amount that one can afford to lose. Most times when gamblers use huge amount of money to gamble their mind is not stable when the game is going on, and fear to lose can make them to withdraw their money even before the end of the game and if the games eventually ends the way they wanted they will feel bad about their decision.
The reason why it is good to playing with amount you can afford to lose is that you won't be on panic when the game is going to make decisions of withdrawing your money that may not favour you. Playing with the amount you can afford to lose, even if you lose it won't be a burden to you that much, than playing with a bigger amount and expecting so much from gambling. Sometimes people get scared of loosing their money because they can't afford to lose it.
