What are the chances of a silent-launched game actually ever getting played on Google Play store?

I've been on and off programming in Unity for about 10 years. Never released anything as I usually get really engaged for a couple months, then abandon whatever I was working on and go back to good ol' gaming in my spare time.

This time, I actually have a prototype that I might see through to launch, but I don't care enough to actually do any marketing or social media or any of that. I have a decent 9-5 and this is really just born out of my desire for quality mobile games launching without mtx or ads.

So my question is the title. Would it just be a waste of time to launch a game no one knows about? Would it ever get played?

ETA thank you for the responses. Despite not anticipating any sort of commercial success, I see it's best to put at least a little bit of effort into the business side.
