You better stop differentiating between paid quartz and free quartz, there is no difference whatsoever safe for the guaranteed gacha, which is unsuable with free quartz.

For rolls, you need to calculate things to infinity, meaning, out of X number of rolls, Y number of servants of Z rarity. If you're far from the median average, it means there are higher chances for you to be lucky, if you're above the median average, it's more likely that you will be unlucky, simple as that.

To make a bit of sense out of this, it basically means that out of all the players, 80% will have pulled AT LEAST 1 SSR after 300 rolls, while 20% will have pulled nothing. Similarly, 99% of the players will have pulled AT LEAST 1 SSR after 500 rolls, that 1% being extremely unlucky.

Probabilistics are deep, very deep, and you can't measure them nor get any conclusive information from your own rolls, so kindly stop yourself from drawing weird conclusions.

This is also why I NEVER buy quartz, safe for guaranteed gachas, because the rates are too low, and that means that you need to spend around 98,000 yen to almost be safe when you want to pull an SSR, but that number almost double for a rate up SSR, so... yeah, no ty.
