Our universe certainly has to allow for the existence of us because we exist, but I don't think it says much more than that.
It's easy enough to imagine on Earth that conscious life never formed and to imagine such without changing the laws of physics. I don't understand anything about our universe that guarantees the existence of conscious life, let alone guarantees multiple instances.
All we can really say for certain is that our universe allows for us. We really don't know how rare we are.
