ELI5: How do bugs even survive in nature?

I just watched a cockroach walk along a ledge for about 10 minutes, hit the end, try to walk up it, fall on it's back, do 360's for about 10 minutes, get back up, do the exact same thing, fall off the ledge this time, hasn't moved since.

How do these things not go extinct?

Insects don't have the "intelligence" approach to survival like us.  They have short lifespans.  A female cockroach can lay 300-400 eggs in her lifetime.  They are quite hardy but numbers is their strong suit.
