Anyone know if the money in streaming is comparable to that of YouTube. Could they be making that Ryan's Toy Review money or is the ad revenue not that great for live services?
It's dependent on a few factors:
1. Subscriptions. This is actually a fairly large revenue stream, especially since Amazon Prime started giving all participants one "free" sub per month. The streamer doesn't get the full profit off it, generally; how much they get is based on their personal partnership contract with Twitch, though as far as I know they always get at least $3 per sub.
2. Donations. This can be a surprisingly large revenue stream for the large audience streamers like Meteos. I wouldn't be surprised if someone has just tracked a streamer's donations over a month's period and summed it up, since it's basically publicly-available (almost all streamers have an on-stream notification when someone donates), less a percentage for PayPal (both in terms of the cut they take, and the assumption of some charge-backs happening).
3. Ad-Roll. Twitch streamers actually decide for themselves how often they want to roll ads, rather than YouTube doing that for them. So, how much money they make off ad-roll actually depends directly on how often they decide to run ads.
As a result--and because Twitch doesn't like partners discussing their contracts--it's hard to say definitively that a streamer with audience size X makes roughly Y amount of money, though even just by tracking the more easily-estimated revenue streams (sub numbers are public, and like I said, donations are trackable) you're probably going to get a pretty robust number for the top streamers.
That said, keep in mind that most pro players don't pull in this large of an audience. As I've said in this thread, Meteos pulls in viewers as much or more based on his personality as an entertainer compared to his gameplay. There's a dozen players better than him in NA alone that don't have as large of an audience, to say nothing for regions with comparable or even better players but less audience interest (hi EU).
