Well said.
We should put our emotions aside when gambling, because emotions make us lose more in gambling than any other gesture. The guy fell under his emotions to place a bet on 1.01x odds thinking that he could go all in and make just 1% more to manage money for some luxury he could be wanting, which made him gamble his entire bankroll and in the end, he is left with nothing. Now no luxury nothing, but all he's got is his failure. This is not a lesson but a stupidity committed by that gambler which no one should do in their life if they want to be a sober gambler. Going all in on such small odds is very dangerous and can cost you your entire life savings.
Aren't you making assumptions about something OP doesn't provide even a tiny bit of information about? Where do you know what the emotional state of this guy was? Perhaps the guy is saying that then night was the best in his life? Nobody knows what he was feeling and who he is and nothing do we know.
Maybe he won the biggest lottery ever before and had a fun night out and appreciated the feeling that losing 1.4 million USD can't derail his life? That must be amazing to have such a feeling. I wouldn't do that too often though
