It is definitely possible to say that this tax looks absolutely unfair and it is just a way for the state to get rich on the happiness of the winners. At the same time, the state does not care that people spend their money on casinos, no one returns 10 percent to them. If I were a gambler and betting enthusiast from Zimbabwe, I would simply play at those casinos that are associated with cryptocurrencies and which, unlike state casinos, do not transfer data on winners to the state.
