It’s also worth remembering that there is a particular type of selection bias in games like this. If you have a less than 50% chance to complete a roll, you probably won’t even bother. You would almost certainly succeed on as many 10% chances as you fail on 90% chances, but you never attempt a 10% chance success action, so you only see failures on the 90% successes.
Not saying that the RNG definitely isn’t broken, but I see this exact same topic in every game that uses RNG, and it is never the game. It is just that some people getting unlucky is a statistical inevitability.
