Also the big vtubers are big because they're great community managers who can navigate challenging balancing act of making people feel welcomed while also maintaining a sense of exclusivity. A lot of indies will reach a point where they feel "secure" and start focusing on maintaining their garden instead of growing it. Any new viewers who discover the chuuba are going to be put off because they feel like they've stumbled across a community that doesn't need or particularly want them. If you can make a new fan feel as important as your first subscriber without alienating the "old guard" in turn then you can safely say you've made it.
