You not only have to to stuff, and publish stuff, you have to tell everyone about it.
From my own experience, I've been streaming myself coding a lot recently, but the only time I get even low single digits tuning in is when I post a link somewhere.
So I guess just be prepared that you can write blogs, stream, post videos, publish software... and people don't take notice. There's a whole self-promotion aspect to it as well.
If that doesn't bear fruit then you have wasted your time though. I don't think that framing this as "increasing your odds" or "having a better chance" is helpful for most people.
If you're starting from zero you're looking for a moonshot, because even if you increase your odds by 1000% the chance of a tangible positive result is still probably ~0.
Blog post is not about "starting from zero" it is about starting from point where someone already did interesting or useful work.
It is also not saying anything about moonshots to get someone super rich or super famous.
