Mathematical calculations of chance in probability theory only work with very large numbers. We don't influence the chance of gods appearing in any way and use fair randomness in the game. Therefore, there's no guarantee that some player won't be able to resurrect a mummy even after 10,000 attempts.
At the same time, we even recorded some of the author's phrases in case someone manages to discover 12 new relics in a row at the very beginning of the game.
This is the paradox of true randomness: it seems completely unfair.
