Trading and gambling probably the risk are equaly same but the difference is gambling pure of luck but trading results are depend on our skill to predict the market and according to the article that his mistakes was always be all in during trading which this can lead him to huge loss and from it he lost everything to crypto but fortunately currently he was on rehabilitation to healing his addicted but he worried this will happend to other people
But the good thing about trading is we can make ourselves improve our strategy get the best results unlike in gambling that we just rely upon luck, nothing else. But what OP has stated was an addiction that causes losses, this becomes a common reason why people fail to reach their goals. I don't know how it feels like that as if you are still in your mind, you can actually control it.  
It is really hard to hear people lose everything in crypto but I think it was good in a way to help them realize that there is no easy moeny in crypto. Many just underestimate the market.
