To be fair, there is now a thorough understanding and computing capability for doing statistical failure analysis. They are not doing this at random. And SpaceX is NOT testing everything in actual flight. See engine testing, pressure testing, static fires, massive instrumentation (tests including flights with gathering data as the primary objective) - all as evidence of that. And they have commented on the wide availability of hardware - currently arriving faster than the capability to try and launch it. So, no, not similar.
