Even if the numbers are accurate (there are still questions about that), it represents revenue from three sources and three sources only: Bits, Subs, and Ad revenue. We also don't know if that's what the streamer actually gets or if it's before Amazon/Twitch take their share - streamers get $0.01 per bit but Amazon charges a 25-40% fee to purchase them, ad revenue is based on a CPM (I believe it's $0.05 per 1000 views), and Amazon takes 50% of subscription money for Affiliates and between 30-50% for partners (a streamer has to negotiate to get the 60/40 or 70/30 split).
And even if those numbers are accurate, they're still only one part of total revenue. It would not count licensing deals like the one with WizKids for the Critical Role miniatures, merchandising for the t-shirts and other CR merch, royalties/licensing revenue from the Tal'dorei sourcebooks, crowdfunding for the various projects like the Amazon animated series, sponsorship deals with Dwarven Forge and Carolina Tables and any of the other companies, revenue from Darrington Press their game publishing arm, etc. It also would not include expenses the company incurs like studio rental, salaries for staff, payment to freelancers/contractors, bills for things like power and internet, tax obligations, printing and shipping of games for Darrington Press, etc.
So basically even if the numbers are accurate and even if they're for revenue and not some other number associated with the account and even if they're representative of actual revenue, we still have no idea how much Critical Role actually makes. Nor of any other streamer on the list.
