I realise that Google places ads in the native Gmail environment. However, when using a third party front end to embed the Google services, how does the company make money off that? When I use Thunderbird to access Gmail or the Google Calendar or when I map my Google Drive to the file explorer, how can Google profit from this kind of use?

They harvest your data for a variety of reasons. 1) they pair your data with your broader Google profile (including search results, ad clicks, website views, etc) to better deliver targeted ads. 2) they train their AI (although that’s an indirect revenue stream, and much more recent).
Remember: if you’re paying for a service, you’re also likely the product.
