$50,000 is at or above the $2,000 reporting threshold, so the payer files a W-2G with the IRS and gives you a copy.
The payer holds back 24% of winnings over $5,000 and sends it to the IRS. It's a prepayment, not the final tax.
Winnings are ordinary income stacked on your other $60,000. Your top dollar lands in the 22% bracket.
Colorado taxes gambling winnings as ordinary income.

More was withheld than these winnings add to your tax. The difference reduces what you owe on the rest of your return, or comes back as a refund.
