500+ reroll pulls and still no s rank

As the title states I have done 500+ pulls on the limited banner for Caesar (10-12 pulls per reroll) and haven’t even gotten a chance at a 50/50 yet. To anyone else who has rerolled for a limited character, was your luck this bad or does mihoyo just have it out for me? I lowkey feel like I’m blacklisted lol but I don’t even know if that’s something they really do, I probably just have abysmal luck
