The nature of "randomness" (or at least randomness according to computers) and statistics means there's really no way to confidently estimate how true the rates are without a sufficiently large (like, tens of thousands or more) sample size, to account for anomalies and the like.

That said, this is a game that can be played mostly casually without having to use golds, there's no (proper) PvP, events sometimes give away powerful 4* servants for free (like this event right now), and overpowered friend supports exist. So despite the sucky gacha rates, this is a game that can mostly be played decently comfortably from start to finish even if the summoning RNG really hates you.
