When you lose (most people, most of the time), you don't have to pay tax on winnings because there aren't any. But gambling itself seems like sort of a regressive tax that preys upon those susceptible to gambling.

Edit: at least with state lotteries the state gets most of the money so it is more like a tax; in the case of corporate sports betting the corporation takes the money and then pays a small corporate tax on it.
