It makes sense. Assuming the average bot toots ~once an hour (24 times a day) and has been tooting for two years, you get on the order (nearest multiple of 5000) of 20,000 toots per user, which works out to 1600 users.
Also, there's a measuring change from active accounts to plain old users. I don't know the proportion that are active, but if I recall right, the fediverse as a whole had under 1 million active users. Assuming 500,000 active accounts that pull all the weight, it's 220 toots per user on average.
