If indeed he spends all that money on one bet and he really loses everything then surely it will give him a long headache but on the other hand if it is a billionaire then they will be fine and will probably just laugh like Neymar did recently where he lost quite a lot in just over an hour.
But as you said, there is a positive side to this and of course this can also be a reminder that in gambling even if the odds are very small it doesn't mean it's something that can be won easily because something like this could happen.
So we better just take the positives for us so we don't play gambling with lots of money. And even though there is a possibility for us to win and it turns out we win, we must be able to stop ourselves from continuing the game and stop immediately before everything changes.
It's probably the best practice not to gamble with a lot of money if you can't really afford it. Getting inspired by these celebrities and gambling with a lot of money will only cost you money while they just gamble for fun using the platform's own money.
And truly, gambling is not good with heavy risks, we should risk sensibly no matter how much we have to spare for the casino. It's good to go with a good strategy and plan and always manage our gambling portfolio efficiently.
You needed such kind of discipline in order not to waste too much time, energy and money for your gambling activities, getting your point with regard to those influencers, they are paid advertisers and what do we expect from them, everything is scripted and even they are showing that they are winning or losing at the end of the day they will receive their paychecks and will just find other company to provide services.
Gamblers need to be more careful, as we all know how addicting this business and if you are careless, you will find yourself losing a lot, maybe not the same with OP, but a lot for a small gambler like you.
