The immigrant owner of a New Jersey convenience store claimed the $338.3 million jackpot in the Powerball lottery Tuesday and said that despite becoming a millionaire, his heart "won't change."

Pedro Quezada, 44, celebrated the golden ticket he bought on Saturday with a televised press conference at the New Jersey lottery headquarters.

The Dominican-born man faced 175-million-to-one odds when he bought a ticket with the correct five numbers and a Powerball.

Quezada purchased the ticket in the same Eagle Liquors store in Passaic, New Jersey where he went frequently to play the lottery and purchase beer.

"My life will have to change with so much money, but my heart won't change," the father of five said in Spanish.

One thing that might not change, though, is that lottery habit. Quezada joked he might still buy tickets "in search of more."

Quezada was shocked when he first found out, reports said. It was only on Monday, when he went back into Eagle Liquors, that he realized his good fortune.

"He didn't know he won when he came in because he stopped to check the board," an employee told the New York Post. "He was shocked and emotional. He said, ‘It's me!'"

If Quezada takes a lump sum, it could be about $152 million after taxes. It was the fourth-largest Powerball jackpot ever.
