No matter how huge the amount you have not won, it does not matter, because you have not won it, so there is no point in even thinking about it. Although, if we are talking about sports betting, there are certainly unpleasant moments when it seems that the match is already over, your bet wins, but then one minute later someone scores a goal and your bet immediately loses. Such situations happen, but it is unlikely that those failed wins can be called really some huge, most likely these wins are not much more than the others. And so that in betting some really serious winnings went out from under your nose, it happens very rarely and then you have to specifically make bets with large odds and wait for a miracle, because the chances of winning are extremely small.
