Yeah, Moontokkym is right on the money (lol, literally).
Making content or offering people services they actually want, and then putting it in a place where it's easy to find, and presenting it in a way that looks reassuringly professional is so very important, and the easier to do or create the thing you're trying to sell is, the higher the odds that somebody else will have thought to do it.
It's vital to either: Offer a thing other people aren't offering, OR to offer that thing but to advertise it somewhere nobody else thought to but has a big potential market, OR to offer that thing but with better value, either because you do it better or because you do it cheaper or faster.
Some people manage to make a living while being utterly mediocre at what they do, but have found a nice little niche they can advertise to, or they can offer prices other people just couldn't because they live somewhere with a low living cost, or their work is actually pretty shoddy, but their marketing looks so professional, with a great logo and a website with nice design and a google-friendly name and wording, everyone gets a great first impression and chooses to use their services or buy their products.
As an example, being an artist who knows about rock climbing has got me work in the past, because I can draw cartoons with accurate rock climbing gear in styles that will appeal to climbers, and climbers know where to find me. I might be the only pro cartoonist they know, so picking me is easier than trawling online for a cartoonist they might not know. Use your secondary skills and interests, or things like your community or languages you speak to your advantage. In that field, I don't need to be the best artist, I just need to be roughly pro standard and easy to get hold of.
But with comics or games art, it's a lot harder to compete because I'm in a place where people can see they have a lot of choice, and a lot of it is really good. In these cases, I'd only describe the quality of my artwork work compared to other people's as "decent", I'm not the world's top artist, so while I am always striving to improve, I focus on the areas where I do have a leg-up, like humour and storytelling, and the consistency and flexibility of my output. Then I have to take my presentation very seriously on top of that. Having a reputation for being reliable and easy to work with helps for getting jobs, and having really polished and carefully designed presentation on my comics helps me get readers, Tapas features etc.
If you want to do pro creative work, learning some basic design is definitely worth it as a general tip for everyone.
