(I'm not sure what this is called, but it is where you draw each scene, and then put them all together to make a movie.)
Animating? Drawing keyframes? Tweening?
Got to say something: The average art school student will not make a lot of money out of their degree. A lot of artists cannot live off of their trade.
Those who can will make a lot of money, but art is generally a rather unstable source of income.
If you are good at doing what people want, then you will make a lot of money, but that might be going against your 'doing what you love' (which is never really specified?), and whether you want to go outside your own morals and joys to earn money will be up to you in the case you get known enough to get these kinds of choices.
All kinds of professional art makes about the same kind of money, at least if you work as the glorified freelance artist that only take commissions and otherwise just stand in your studio and work your genius, which the drawing-painting-sculpting implies to me.
A better choice if you want to live off this would be to become either an illustrator or a designer. Animators earn well, if they are good at what they do and better at getting the jobs, and would earn you a job where you would wake up in New York and go to bed in France, depending on what job your are working, but to get there, there is a lot of hard work to go through, and most people are stuck at the tweening stages of animating, which is not as fun. Also, you have to count on working on projects instead of having a real job.
As for Illustrators, there is a good deal of variation of what you will be working on, and if you have a broad style, you would be able to do well in this field, which can earn you enough to live of it, though it tends to be hard work as you will rarely be given free reigns on what to do. Same goes for concept artist, which I guess falls into this as well, but at least gives some kind of freedom inside limits. But it does take a certain kind of person, I guess, and a broad and varied style of art and way of working.
Designers might be another good choice, they tend to go for clean art, but will have to work with people who have no aesthetic sense (and these people will be the ones with the money). Web design will probably be the major in this field, which might mean a bit of programming also would do you well.
Either way... It is a lot to consider, and specifics might be good as well as examples if you want proper advice. If you just want answers, well keep on this.
