Post-high-school college attendance is likely to cause you to be seen as a transfer, not frosh, applicant to many colleges. I.e. if you attend an art college after high school, you would be a transfer applicant to most other colleges. For highly selective private colleges, it is often much more difficult to be admitted as a transfer applicant than as a frosh applicant.
Unless your parents have donated a building or some such to the college, it is rather difficult to be confident in being admitted to such a college.
Note that some non-art-specific colleges do have art courses and majors, including animation courses. For example:
