It doesn't look like this chart includes territory fees, and the territory owner makes 70% from that fee. Not that it comes close to paying for the monthly cost - if your fee is 100 sats, you'd need a little over 700 posts to make up for the cost.

BUT, there are roughly 100k sats in daily rewards as well, and I don't know how it fully works, but I believe the sats your territory makes get counted towards your rewards rank. @k00b might need to confirm that one.
