Taxes are irrelevant, You file a form 1040X to adjust your taxable income and get that money back from the IRS. He probably never even saw that money anyways because likely the casino withheld taxes (I assume that's what they do, I don't gamble) As far as spending, I thought the same thing until I read the article, he's already a multimillionaire, "A gambler by profession, Ivey billed himself as the “Tiger Woods” of poker; he had won more than $6 million from several tours on the World Series of Poker and another $19 million through years of online poker."
