What is an instance? what is a federation? what is a server? can someone please describe in simple terms how this all runs and how we as users navigate it?

Yes, but technically no. The full name includes the instance, for example iOS@example.instance.
Similarly, you had multiple subreddits dedicated to a single topic, with slight variations in their name.
I recommend to subscribe to anything which seems interesting (including duplicates), then unsubscribing from annoying stuff.
