Unless you use an “incognito” or private tab when you do your search, your previous personal search history has a big impact on the results you see. That’s been the case for a long time.
Google has apparently found it pleases more users that way.
Google isn’t always the cleanest search possible. I find it repeating many older results on new pages of results, and wish that they had an option to suppress such repeats, because I have to keep paging more than I might otherwise want in order to find something that is more obscure.
