I think you missed the point.
Most people know (or at least heard the phrase) that the house always wins.
However very few realize how big are those winnings, perhaps if they would take news like this into account it would dissuade them from gambling or from thinking they "can beat the house".
And regardless of this specific point - taking so much money like this is not something to applaud, this comes over the expense and misery of people who if they could wouldn't be in their current spot in the first place, but the "house" took the best of them.
Sure but it means you should just make gambling illegal. As soon as it's legal it means some people will extort money from others. That's the very basic nature of gambling.
