The football fan, 17, plans to spend her winnings on a shopping spree, a holiday on the party island of Ibiza and a season ticket for Scottish Premier League side Hibs.
Park, who lives in Niddrie, Midlothian, also has her eye on a customised white Range Rover with a pink interior - although she will need to pass her driving test first.
Understandably, she was shocked to discover that her very first lottery ticket had come up trumps. "I had to phone Camelot to confirm my ticket win," Park told the Daily Mirror.
"It was such a shock. I still didn't believe it even though it had been verified. Although my family and friends believed me, they almost couldn't believe it was true.
"They thought it was too much of a dream as well. They're still in shock."
Even with a million pounds in her pocket, however, Park intends to stay on at her job at the Scottish Council for Voluntary Organisations.
"I'm going to keep my job on," she said. "It's only a nine-month job and they're going to keep me on for another six months, so I feel like I have to give my thanks back to them."
"It'll change my lifestyle but I don't think it'll change me," she added. "I'll still be the same person that I've been for the past 17 years."
Other teenagers to have scooped million-pound wins on the lottery include fellow Scot Ryan Kitching, 19, who found his winning ticket only after being ordered to tidy up his room by his mum.
Not all the young people who win the lottery live happily ever after, though. Callie Rogers, who won almost £2 million in 2003, has since said that the money "ruined her life".
