Transcript for Massachusetts woman quits job after $758.7M Powerball win
now to the country's latest mul multimillionaire Mavis Wanczyk, quickly coming forward to claim her prize after Wednesday night's Powerball drawing. It topped out at more than $758 million but Mavis opted for that lump sum of over 480 million, meaning she will walk away with $336 million after taxes and ABC's gio Benitez is at the Massachusetts lottery headquarters with more on this very happy story, gio. Reporter: It is, indeed, Amy. Good morning to you. She now has so much money she's worth more than the gdp of some small countries and this morning she's just trying to make sense of it all. This morning, the biggest single ticket jackpot winner in history is a 53-year-old mother of two who's already quit her job at the medical center she's worked at for 32 years. I have called them and told them I will not be coming back. Reporter: Mavis Wanczyk decided to take the lump sum after taxes that's $336 million. Today as I'm driving here I'm still like, this is not true. This can't be and then now it's like, ah, I am a winner and, ah, I'm scared. Reporter: Well, she's still not as rich as Oprah whose net worth is equal to $3.1 billion but close to Celine Dion, Beyonce and Barbara streisand and surpasses Taylor Swift's 280 million. It is unusual to hear so quickly from a winner, especially in Massachusetts, a state that allows winners to claim a jackpot anonymously through a trust. She said she just wanted to get it over with. Going against conventional wisdom works for her. My numbers were basically random like maybe with our birthdays maybe one from here, one from there. Reporter: Ignoring common advice about not picking numbers based on birthdays because those numbers only go up to 31 but Powerballs go up to 69. Luckily for her it worked out. The highest number in her winning combination was 26. And she says the first thing she's going to do is pay off her car but other than that she's got no plans. She says she's just too overwhelmed. Gio, thanks for reminding people not to listen to our advice about the lottery. You can pick whatever numbers you want apparently. I love she called her boss. That was very nice of her.
