This kind of event is just like an imagination because everyone knows that nothing is 100% certain in sport betting or casino. the only thing that can make me go all in on a bet is if the person that told me agrees to refund me if it loses. if this is agreed upon then i can borrow some money to play but these things dosent really happen like that. i have seen some people being scammed with this kind of idea that a game is 100%  sure in the name of fixed game and they pay for it but eventually lose.
