Free will vs predestination is an irrelevant debate (Christianity)

I was thinking about the free will vs predestination arguments that go on in Christianity and I realized that regardless of which side of the debate is true, God still knew that most people would not make it into heaven (Matthew 7:14 narrow is the gate and difficult is the way that leads to life, and there are few who find it). I assume that because God is all-knowing, he would’ve known this even before creating humanity. Therefore, by creating humanity, he was guaranteeing that some people would not make it into heaven, regardless of if it was because of their free will or predestination. So, the free will vs predestination debate really shouldn’t change people’s perception of God, he knew the outcome and still let it play out.
