She selected the annuity option. Lottery winners can usually choose to take all of the money up front (lump sum) or over X years (annuity). Because she’s only 18, the annuity option might make more sense. Assuming she lives to age 80, she’d get $3 million (give or take) nominal dollars over her lifetime vs. $1 million up front. This doesn’t take time value of money into account where $1,000 in 2080 might only be worth, I dunno, $250 in today’s dollars. But either way, she won the freaking lottery. Wish I’d bought that ticket.
I thought it's a one time thing (the ticket)
You buy it, you win
If you want to win again, you gotta buy another ticket
