I think everybody has the chance to get rich here, you forgot to mention the word quick. Quick will be for most, not the case. The process takes time, and it is all done in snowball mode, little by little it gets bigger. You need to post good content, ideas, hobbies, but it has to be original.
If you put it into job perspective, then it will be hard, as most will notice it. People don't like to be sold something, they like to have the choice. If you put passion and don't ask for anything, followers will come easy.
