I'm not 100% degoogled, but if Google deactivated my account tomorrow, it wouldn't be a big deal. I've migrated everything important away from Gmail. Gmail is basically just my spam box now.
I also have Chrome installed on my PC for testing purposes. It is my browser of last resort, only used on occasion when I suspect my normal browsers' ad/tracker blockers are breaking some site.
Google Maps is hard to get away from because nothing else has all its key features, and a lot of alternatives also use Google's data so they're not really more private. For example, I don't know of any good public transit apps that work in my city and are degoogled (though to be fair, it's been a few years since I reviewed the options).
