Yes, I'd certainly want to win the lottery. I try every once in a while too.
But I wouldn't blow it on cars or useless crap (although I'd certainly buy a few knives). Depending on how much I won, I'd buy a house (just a regular old house, no mansions), one for my parents, and then set up a machine shop and spend the rest of my life making custom balisongs and autos.
I'd be willing to bet that those who get big lumps of cash, then go bankrupt are the kind that throw parties, buy expensive cars, buy property beyond their needs, then soon find that they run out of money and can't afford the upkeep (insurance, property taxes, etc) when the well runs dry. And I'm sure that there's a few that end up with drug problems to expidite the money loss.
