The audience you need to make good money on YouTube, without external deals, is orders of magnitudes larger than on Twitch, though.
It’s true that getting a large audience on Twitch is really hard nowadays, though. Seems like it was a lot easier a couple of years ago, not sure if it’s just because of changed algorithms or because of market saturation.
No, but the point is that tv shows or movies generally don’t pretend like that.
