Confused on how to report Daily Fantasy Sports Winnings

I am very confused on how to report my Daily Fantasy Sports Winnings. I received a 1099 from Draftkings for $4599.

The article below by TT says to report as Other Income.

However the IRS has stated they view DFS as Gambling. If that is the case, why do i receive a 1099 and not W2-Gs?
