Can trading help me earn a basic income?

Avid and professional traders, or at least those with the loudest voices, often suggest that this job has been their gateway to fortune. I'm well aware that this job requires a great deal of commitment, discipline and practice. But my question is this: is this a reasonable way to support one's basic necessities? That is, eating and paying the rent. I'm not talking about affording an island 🤨 I'd like to be enlightened before considering dedicating more time to it. Thank you for your help.
