You would be surprise how much partnered streamers make. For instance CohhCarnage (great guy and businessman) has said he has about 4500 subscribers. People pay $5.00 to subscribe to a channel and twitch gets about half. So Cohh pulls in about 11,500 a month just on subscription. This is not including tips, his website subscription "cohhilition.com", or ad revenue. I would suggest finding a streamer you like with a decent size channel and watch it. Even if you are not into watching people play games the business side of twitch is very interesting.
