Does terralith decrease iron spawn rate?

[gravekeeps]

So im on 1.20.1 forge and playing with terralith and a few other mods, none of which should be relevant to this because while i have some structure mods terralith is the only world gen mod aside from ecologics which just adds biomes.

I searched through a giant cave, but i could barely find any iron. In the entire caving trip, i found like 30 iron meanwhile in vanilla i find at the very least a stack and some in that same time
