I have to say I had no clue what's a career or my career when I was your age. Same happens to lots of others posting similar questions on this platform as well. However, you are off to a good start simply because of the early awareness of career.
I would recommend search keywords like "Career", "Goal" in the search box and take a look at the filtered Q&As.
- what do you like to do / what don't you like to do?
- what are you good at / what are you not so good at?
- what would you like to learn more about / what do you KNOW you don't want to learn more about
Use these questions to help yourself find an idea of what aligns both with what you like and what you feel your good at and let that guide your exploration in college! This exercise can and should be repeated along the way as you consider joining clubs, majors, classes, internships, and ultimately a career.
