Not true. We have no firm grounds to even count species for the 3.3 billion years before 540 million years ago. If average life span of a species is 5 million years, and did not simply change gradually into a daughter species, then only 95% ought to be extinct in 100 million years. If 10 million years, then 90%. if sizeable fraction of species are continuous evolving into daughter species and not just dying off leaving no descendants, then the rates would be lower.
