Are all these thousands of lemmy servers useless?

Please elaborate, how is "every instance is sharing in the traffic to browse the fediverse". I didn't find it nor in AP standards, nor in activitypub_federation lib docs. If there is some mechanisms of balancing inside the lemmy's code, would you mind pointing it for me?
Looking into the database, it contains many thousands of posts. I’m assuming this is stored in the local db for serving it to instance members. So when you open a post from instance B on instance A, A fetches post-data from B, stores it in A database, then serve the content from db A to the browser
Yes, you are right. If this instance has members. A server will actively fetch "foreign" content and cache when this instance's user asks. But aside of top 10 servers, there is no profit of having more until they have a couple of dozens of users. If any server would have been able to "delegate" request handling to less busy servers, it will be a solution for this uneven load.
