When I look at my number of follows, I see 80, and those listed include people both on this instance and on others.
If I look at the number of follows for another person on my instance, I see their follows both on this instance and elsewhere.
If I look at the number of follows for someone who isn't on my instance, it only shows the number of people on my instance that they follow, and only people on my instance are listed, not the people they follow on their instance or any other instance.
You can see an off-site person's full list of Follows if you go to https://instance.url/users/username/followers - which you can get to from the profile page linked in any particular toot, then click "followers."
