Probably not...My own use of wording.
Random events as an example, would be as written above in OP. Asteroid smacks the planet wiping out the Dino's. This allowed the small mammalians to flourish, literally. Evolution plays its role and here we are today.
No Asteroid, no us in other words, so a random event is the cause. One could argue that asteroid was pre-determined by who or what to allow the right conditions for a bunch of really non symbiotic Humans to play virus...
The early Primeval soup theory, random chemistry at play, non specific, right conditions and whalla.
Hope that clears up the meanings for you.
