Forgive me if this is an overly simplistic view but if the ads with cookies are all served on Google's platform say then would all those ads have access to the Google cookie jar?

If they don't now then you can bet they are working on just that.

They are usually separate things. Cookies are produced/saved locally, to be read in the next visit (by the same website or maany websites basically forever unless you use firefox containers or at least clear them once in a while). There's also local storage which is different but can also be used to identify you across the web. Ads, trackers, all of these categories are often made of many small components: you read a single article on a "modern" newspaper website, hundreds of connection are being made, different tiny scripts or icons or images are being downloaded (usually from different subdomains for different purposes but there's no hard rule). It's possible to block one thing and not another. For example I can block Google Analytics (googletagmanager) which is a tracker, but accept all of Google's cookies.
