Tax questions slot wins

A reworded question.

I had a question about paying estimated taxes after I won a hand pay on a slot machine last week, but I worded it wrong. They did not give me a W2-G nor withhold taxes. My question is, should  I pay the taxes right away as estimated taxes, or can I wait till the end of this year? The lady said I would receive a W2-G next week. Also since it was in Nevada, and I don’t live there will I need to pay Nevada taxes for 2024?

Also why do I have to enter gambling losses when in the end I’ll take the personal deduction?
