Sorry but I think you might be wrong, no one will bet with $1.4 million dollars for fun, from all indications, it's crystal clear that who ever is behind that bet simply was betting to win money, looking at the odds of the game in question, this is the type of bet we assume to have a 99 percent chances of winning, which means it's just 1 percent chances of losing, in this type of bet, chances of winning is high, but betting with a very low amount isn't really profitable since the winning will be so Insignificant, so to make a good winning off game with this type of odds, it's always best to bet a really high amount of money, and that is exactly what the gambler behind this bet did, but unfortunately for him, luck wasn't on his side.
I Personally will assume that the gambler did this bet with every single penny on his bankroll, no body will bet over a million dollars for fun, no matter how rich the person is, money is not that easy to come by.
But like you said, lets hope that he is OK with his life, cus this is the type of lose that often lead people to killing themself.
Very well, this parten of play is far from fun but for basically winning a jackpot, although we can not dive into the aspects of possible case of gambling addictions since the guy in the story have no prior history that is mentioned in the ops, but for a 1.4 million wagerer something big must have been the motivations behind such an action and possibility that he is a heavy wagerer but will missed calculation this time around, although the games may have been in his favour from the beginning but towards the end part he may have run out of luck at that time, many times we should look more inward when situations like this happens and not be too quick to Judge things since we have some elements that we have to take note of and try as much as possible to avoid making false conclusion.
But the certain thing is that this particular gambler's has his decision way far from being for fun and nothing but possibly he is indebted and want to double the present funds and choosing a low odds gave him some form of confidence which did not last a while for him the whole time, well let hope he recovers from the huge lost and being able to caught down the level of his risk taking at every point in time.
Business as usual but then this time he run out of luck and this is where the situation have landed him, lets hope that he is able to recover, if he have indeed gone extra mile to throw up such huge amount of money, and what is his frame of mind right now that he has this situation at hand.
