Discoverability matters much less than you think because discoverability is a zero-sum game. If the algorithm favours one type of creator, it necessarily means that it takes 'it' away from another - so the more creators you pile on, the harder it is for any one of them to breakthrough - regardless of how awesome your discoverability algorithm is.

There are some caveats. If the audience is growing relative to the number of creators, you (on average) still have a chance. YouTube also has a huge audience and wide variety of content (much more than Twitch, which is heavily focused on video-game streaming), so it's possible that there are some niches that can still be exploited in a way that you couldn't on Twitch, which is heavily focused on a small number of niches.

None of that takes away from the larger point - it's a race to the bottom when trying to be a viable creator, and the probability of building a big-enough audience to make enough money to even partially support yourself is very very low.
