I'm hardly a marker of success but I can at least attest to growing slowly over time. I never had anything remotely viral/successful but I just sort of keep doing my thing, posting consistently and making my games and youtube channel for the past 3 years. Every now and then I get a new subscriber until it eventually went from 60 to 900+ on youtube. I still only get handfuls of views and maybe 1 comment on most of my videos. And the traffic I get from youtube still in a drop in the bucket to the natural traffic I get from itch.io (which is also a steady drip). Just focus on doing what makes you happy imo. Make things you're passionate about, try to use relevant tags and put your best foot (presentation) forward. That's what makes me happily keep doing gamedev anyway.
