All authors start as no-name authors. Before someone has published their first book, no one has heard of them.
(Unless you're already a movie star or something, but that's not what we're talking about.)
There are plenty of people who started making good money and ranking high on KDP. Amanda Hocking, Hugh Howey, and Jacinda Wilder comes to mind. Every month the KDP Newsletter has an interview with such a person.
What all these authors have in common is that they wrote a lot of books, wrote really interesting books that people told their friends about, and did a good job of marketing. Amanda Hocking left KDP for a traditional publishing house because she said that she was spending 8 hours a day on FB, answering fan emails, sending out tweets, etc., and wanted to be able to spend more time writing, letting someone else handle publicity. (The trad publisher picked her up however because she'd already become a best-seller on KDP, doing all her own publicity.)

Never heard of it...are there clinics you can go to for that?
No, but somebody should build a clinic to treat old writers soured by years of reading and writing sarcasm, satire, irony, and outright cynicism so we can again become the productive members of society we once were. I'd be the first in line.
