You won while in international waters.   But you still have to enter the W-2G on your federal tax return and on the state return of the state you live in.

No state taxes were withheld in box 15 of the W-2G?  Then leave boxes 14, 15 and 16 blank (empty)

Gambling losses can only be deducted up to the amount of the gambling winnings.
Gambling winnings are reported on Form 1040 Schedule 1 on Line 8b. The amount from Part I of Schedule 1 Line 10 flows to Form 1040 Line 8.
Gambling Losses are reported on Form 1040 Schedule A as a Other Itemized Deductions. Gambling losses are not a one-for-one reduction in winnings. Your total itemized deductions reported on Form 1040 Schedule A must be greater than the standard deduction for your filing status to have any tax benefit.

If you are a US citizen, all your world-wide income is subject to tax in the US and in your home state.  But if you did not have state tax withheld, leave that blank when entering the W-2G.  The income will still be added to your state income tax (if you live in a state with income tax) and the tax due will be added to anything else you owe in that state.
