I thought we were doing napkin math.That's not a Turkish average salary and it took an investment of 2 million euros according to an older interview with Armagan to make Bannerlord. Steam also lowers their tax with more copies sold. You also have to take into consideration regions, in Turkey you can buy the game for 16 euros, in Russia about the same.
Also I just googled the information, didn't spend more than 5 minutes on this lol.
