I do get where mathanxiety is coming from on this actually.
It’s not that art is worthless - art has both a social and a practical application. I think it’s more that just blindly following a passion without thinking about how it’s going to pan out as a job aid isn’t always the best idea.
What gets people success in life I think is a basic level of intelligence plus people skills plus grit. Obviously there are many exceptions- some people are so privileged that they can’t fail. Some have zero people skills but a niche skill that makes them in demand. Some are connected and some are lucky.
But in general, just following a passion isn’t enough. If you follow that passion AND have a think about things like networking, crossover with other areas, where can your skill set take you, etc and you grasp opportunities as they arrive you have a higher chance of being successful than just drifting through. And that goes for all subjects not just art.
So I would look at what she enjoys doing and then think about which jobs and careers use those skills. If it’s art, is there anything that she specifically likes? Technical drawing, digital design? Illustration? Animation? Surface design? Sculpture? Etc etc. How can she get practical experience in such an area while studying? That’s what will get her ahead of her peers.
I loved art and I was good at it - I ended up a scientist and now I work in industry. I indulge my creative side in my spare time. If money was no object I’d switch to solely creative tomorrow.
It isn’t either or. She can follow a passion and be grounded and directed and practical
