Streaming is more difficult since you have to create a viewership from basically nothing, while sites like Twitch, Kick, and Youtube have a massive userbase for streaming content. You can join a peertube instance but there seems to be little content and few users. Owncast is ok, basically more like hosting your own Twitch channel, but again you would need to byo userbase. You can use mastodon/kbin/lemmy to build up a following. Not sure if anyone has made a stable income from these services though.
