Even though there is the possibility of losing such a huge amount as huge as 1.4 million on bets vut to see such huge confidence in bearing such a high amount on a bet based on the sure odds and end up losing this is a lesson for everyone to not trust too much on odds.
We must remember that in this world there is not such a thing as a sure thing, an example of this are arbitrage bets, another name they have is sure bets, and they have this name because if you do your job correctly regardless of the result of your bets you will make money, however you can still lose even when making those bets, not only you could make a mistake but each sport has their own specific rules and each casino has specific rules to deal with special scenarios, so even if you do everything correctly you can still lose, making the name of sure bets incredibly deceptive.
