Need help understanding

Hello everyone! Relatively new trader here (about 9 months into my journey). Don’t want to divulge too many personal details but I recently got funded. I’ve had this question for a while and I’ve never really gotten clear cut answers on it (because I think everyone’s journey and experiences are different), but just out of curiosity (no impatience or rush to get to this whatsoever, I am enjoying the slow process of improving and growing my account one small trade at a time), is making a lifestyle off of trading something that is actually achievable? Most of these online trading gurus are making their money selling courses it seems - plus it’s so easy to fake things online for viewership so everything there is taken with a grain of salt.

But in terms of creating a life for yourself, earning a steady “salary” every month - being able to buy a car, pay off a mortgage on a house, have your entire lifestyle be funded just by trading for yourself. Is this something that is truly possible? Or is it an exceptional situation to be able to do that, and most people should expect to use trading as a secondary stream of income?
