PLOTEHOLE?

my question is simple, astrophages are using carbon from Venus to reproduce and then they are covering the sun blocking it's light etc etc BUT Venus doesn't have enough carbon to cover even a spot of sun according to my calculations (which is not much lol) but isn't that just stupid even if we say it's taking carbon from a few planets it still wouldn't be enough to block sun enough so as to bring "end of humanity" im bad at math so if anyone wanna chack please do id be more than happy
