Google generally doesn't weigh in as it's all handled between the uploader and the claimant. If the claim is disputed by the uploader then the claimant can accept/reject that dispute. The uploader then has the chance to appeal; if they do so then the claimant has to either release the claim or escalate to a DMCA takedown. Of course if it gets to that point then the video is coming down and no one will be making money.
