Is it realistic to get 10,000 gold by level 1000

I have give it a try but I'm not receiving 500 full gold bars. I think maybe it work for some people and not for some people.

Your trick to always get 500 gold bars with the Candy Royale challenge never worked for me. The event always becomes unavailable when there are only 7 levels left to complete the episode, even on previous versions of the app.
