What you're describing is more commonly known as the "Prosperity Gospel" - https://en.wikipedia.org/wiki/Prosperity_theology - which is a niche theology that claims believers will experience "health and wealth" on earth.

Predestination is a much more mainstream Christian doctrine that has nothing to do with "good people" vs "bad people", or even "good actions" vs "sinful actions". Predestination means some people are "destined" to salvation and others are not.

Predestination is a challenging theology that has to balance God being all knowing (omniscient) and free will.
