Tracing "Do gas stations get a cut of lottery winnings?" leads to the prize table. Lottery prizes come in tiers, from a jackpot for matching every number to small awards for matching a few. What reaches a winner depends on the tier, on how many people share it, and on what is taken off before payment. After the draw, winnings can often be split, passed on or left to heirs, and each of those steps has rules of their own.
A prize for matching just two numbers exists in many games, often a free ticket or a small fixed sum, while other games start paying at three. The prize money in shared tiers changes with sales and with how many people win, so the same match can pay very differently from draw to draw. A prize calculator on the organiser's site takes the matched numbers and the draw and shows the amount for that tier.
What is deducted from lottery winnings depends on the game and the place: tax is taken at source in some places, while other organisers deduct nothing at all. Retailers take no slice of the winner's prize itself. Shops, kiosks and gas stations that sell tickets earn a commission on sales, and many also receive a small bonus from the organiser when a big winning ticket was sold at their counter.
