Your parents didn’t attend college in the US, but that doesn’t mean that they can’t learn what colleges are looking for in prospective students.
Have your parents and you visited any of the campuses that you are interested in attending? All of the campuses should all have admissions info sessions where your parents and you can learn about the admissions process. Many schools offer virtual info sessions. If you are thinking of attending college at a young age, I would make sure you visit in person to understand the culture of each campus. For example, SMU has a large Greek system and has a pretty active party scene.
In general, colleges are looking for students who will be successful academically, socially, emotionally, and for students who will contribute to their campus community.
