What part of their story are you referring to? There are lots of indie devs that appear to be having great fun making games and doing well to boot. Valheim, Black Rock Galactic, Celeste, Dead Cells, Papers Please, Stardew Valley, Enter the Gungeon, Don't Starve, Undertale, etc. were all pretty bit hits, certainly made their developers millions of dollars, and AFAIK the developers were having fun making them.
