Definitely I misunderstood, you were perfectly clear, I just now realized looking back. Neither of the companies provides you with option to sync Google and Icloud. Those are two independent servers having your personal information and allowing you to save and protect that calendar information from each other as well. So while phone is allowing you to view your calendars together in phone interface, none of the information is exchanged between Google and Apple.
Now as far as your PC - Icloud allows you to see your calendars in Outlook, there is no other client that I know it is compatible with so it is the next part I am unclear on.
Either you are asking how to see those Google calendars in Outlook and in that case I would recommend to discuss that with Google/Microsoft support or you telling me that your local Outlook calendars didn't upload in to icloud and in that case follow these steps.

If that article is not helpful I can recommend to take that discussion to thread that supports PC with icloud.
