How do you know it is unlikely? Currently, it is a fact.

Let's assume there was a state were any universe was equally possible. When was that state? Does it make sense to describe states before the big bang, the beginning of time as we know it?

Even if it does make sense and our universe is very unlikely. It still can be pure luck (what I was trying to say with the parents example). The existence of our universe is no hint of its likelihood.
