This is false, but it's also built on a faulty premise. The word translated "predestined" only occurs a handful of times so to make a rule based on those few occasions is not well founded, especially building an entire system on that rule.
But if we look to other appearances we see it is used of situations in Acts 4:28, 1 cor. 2:7 and seems to directly be referring to the method of adoption in Ephesians 1:5.
Even in Romans 8 it could arguably be the method that is in mind with foreknowledge being the principle bridge between individuals and what follows. It and Ephesians 1:11 are the only places where it conceivably refers directly to people and in both cases there's ambiguity as to whether it is a direct selection or if it's speaking of adoption into Christ as what's in mind.
