This statement does not make sense. If they only survived 4 out of 5 extinction events then there should be no more sharks alive today.

They weren’t around yet during the first one

OK, I think I get it now. But it sounds a bit confusing. If you are listing events that sharks were not present for, then you might as well say something like Sharks survived the Big Bang

Kind of? It’s referencing a well known set of mass extinctions that are talked about together, the ‘Big Five’, but it also is worded poorly. Instead something like “Sharks have survived the most recent four of the ‘Big Five’ mass extinction events.” might be better?
