There is to be an issue here bro the player knows about the odds and then he still bets meaning he knows the risk here so it is part of the game in my opinion. and if you ask me how a good gambler should avoid such mistakes? the answer is there is no mistake here it is just probability and then he chose it from the beginning.
Although 1.4 Million USD is definitely a lot of money but just imagine if he win he still make a decent profit there haha
When I was a gambling addict, I looked for strategies to win. I went from 1x2 to other ways to bet. Then I noticed that I decided to like 1.02 odds which was very common. It encouraged me to bet with huge amount of money. I might be winning but at last I will lose more than win and the losses are very huge. One of the worst mistakes a gambler can make is to gamble with this little odds like 1.01.
It is easy to think about those bets with low odds as a sure thing, but we must never forget that such a thing does not really exist when gambling, since the risk of an event not going our way will always exist, and what is worse is the sense of security those bets can create, as when you finally lose you will be unpleasantly surprised by it, a circumstance which could make you to incur on further mistakes as you try to recover the money you did not expected to lose.
