Gambling winnings are taxable income.  Losses are an itemized deduction.  If you do not have enough itemized deductions to exceed your standard deduction, your losses will have no effect.

Gambling winnings are reported as other income on the 1040 and gambling losses are reported on Schedule A as Other Itemized Deductions.  In order to get credit for your losses your Schedule A total must be more than the standard deduction for your filing class (Single/MFS - $12,500; MFJ - $25,100; HoH - $18,800).   If you did not have more than the standard deduction, you did not get to take your gambling losses.   Which is why you may have a Federal tax increase of $600.
