Yes, it does seem like a lot of processing. Now google any word and see how fast it returns 200,000 results. Consider that Google delivered the same experience to millions of other people at that same time. Then consider what size drop in what size bucket the processing you described really amounts to.
It can process all of that easily on its servers. But there should then be evidence of this very large quantity of data being exported out of Chrome and uploaded to Google, which I don’t believe there is.
There are some other difficulties, too: no two shopping platforms encode “user completed the order” in the exact same way, so performing that analysis is actually quite hard and not nearly 100% accurate, even if you can get the complete browsing data.
