Most of the money is made selling professional cards and high performance data centres, Nvidia is having no issues at all selling its high end enthusiast cards and you can bet the profit margins on them are a lot higher then low end and mid-range.
It does seem strange AMD hasn't even tried to challenge Nvidia with a RX490 type card, with DX12 being used more and more the lower CPU overhead benefits AMD a lot (it doesn’t help product lunches when review sites like Toms Hardware continue to benchmark rubbish like Project cards which clear doesn’t utilise AMD’s hardware correctly which shows it in a bad light from the get go). AMD obviously has their reasons for not lunching an enthusiast grade card but I would like someone to challenge them on this at the next shareholders AGM.
