I was going to say this as well. To say the human brain is a statistical machine is infinitely reductionistic being that we don't really know what the human brain is. We don't truly understand what consciousness is or how/where it exists. So even if we understand 99.99~ percent of the ohaycial brain, not understanding that last tiny fraction of it that is core consciousness means what we think we know about it can be up ended by the last little (arguably the largest though) bit. It's similar to saying you understand the inner working and intricacies of the life and society of new York city because you memorized the phone book.
