I don't think motor skills are a good object to use in an argument about verbal vs non-verbal thinking. We have large regions of our brains primarily dedicated to motor skills and you can't argue that humans are any more talented or capable at controlling our bodies than other animals, we're actually rather poor performers in this area. You're right to say that you aren't conscious of the very highly trained movements you are making because they likely have only a tenuous connection with any part of your brain that we would recognize as possessing consciousness or thought, they are mostly learned reflexes and responses to internal and external stimuli at this point like a professional baseball player who can automatically catch a ball flying at him before he's even aware of it.
