They are lucky. The odds of winning the lottery are astronomical. It is pure luck that they won.
Now the dire straights they end up in are their own fault. If you have never had 40 million dollars (or whatever you win), you should go see a financial adviser to help you figure out how to live the lifestyle you want and never have to work a real job again. They are in dire straights because they did not realize the money would not last forever, they over spent, and didn't understand the tax implications. That is their own fault for not doing the research.
