Braje has an important point. There are a few disadvantages to taking the deduction:
First, your winnings raised your AGI. That can phase you out of credits, most of which phase out at certain AGI levels, even if your tax is offset by the deduction.
Second, you have to itemize your deductions. Your standard deduction, if married, is 12,600. Unless you have a variety of other deductions, you may normally take the standard deduction. The gap between your potential itemized deductions and the standard deduction is lost deduction space - you get no benefit until you're over the standard.
Third, you can only deduct an amount up to gambling winnings. Any additional losses give no tax benefit.
Fourth, you have to have losses. Which kind of eliminates the advantage to winning in the first place.
