Diamonds feel too rare, almost like they accidentally made the spawns post 1.18

So i just made a new survival world today on java addition, and I was strip mining for hours. I used 2 diamond pickaxes from diamonds I found in blacksmiths and I was using those only for strip mining and I didn't find any diamonds at all on y=11. I downloaded an X-ray pack to see if I was even near any, and I saw 3 patches in like 30 chunks
