No, but filter strength is likely to be exponentially distributed. The universe is big, intelligent life seems to be rare from where we stand, there’s many OOMs of filter to explain. But the claim/premise is that statistically it’s likely one (or a small number) of factors explains more OOMs of filter than any given other, and we don’t know which one(s). So you can have a lot of things that each kill off 90% of paths to potential spacefaring civilizations, but not as many that kill off all but a billionth of them, or we probably wouldn’t be here to ask the question.
