Why doesn’t my mom want me to go to college?
You need to have a serious conversation with your parents to try to dig out the real issues. Is it an issue of money? Jealousy because they did not pursue any education? They grew up in an era when attending college was far more common & far more accessible than for their parents' generation. Community colleges were already well established & developing a growing range of programs. There's no good reason why they "Don't understand much about college." It seems from your description that they have some bias against education, and such is often rooted in jealousy, resentments, etc.
At their age they probably have no idea that there are resources out there to help low income students get into college. As the others stated, it’s probably the fear of the cost. Explain that there are grants and scholarships you can use early on and if push comes to shove there is also loans, though these should be used as a last resort. They don’t have to be worried about costs. Also, at their age, getting a job was expected when they were young and college was a luxury if you could squeeze it in. Old dogs do not in fact learn new tricks. All they know is what they grew up with and anything straying from that is unnatural. Just don’t talk to much about your plans until it’s finally time to enroll.
Can the afford the cost of sending you to college? If not, you need to start inquiring about financial aid. Contact the school you are interested in and speak to someone in their financial aid department. Maybe you can arrange your own financing for college. Good luck to you!
It’s all about money
You do not have to go to college to have a good career. It probably is not that your mom does not want you to go to college. It probably is that you parents know they cannot afford to pay your tuition. Your parents are old enough to be your grandparents. I had older parents too, but both of my parents had college degrees. My father was university faculty. College was different in the 1930s and 1940s when they were in college. College is different now from when I was in college in the 1970s, 1980s and 1990s. Ive been to college in the 2010s, College is changing at relatively rapid rate exponentially. Your parents have no college life experience. They don't know how to advise you. That is why you should see your high school guidance counselor, especially the college guidance counselor as soon as possible.
