People don’t get admitted by chance (luck) to the schools on your list. As an international applicant, you would need to have stats well above those of the average accepted US student for these schools. And if you need financial aid, very few schools provide that for international students, plus they are highly selective.
You can get better advice form here regarding your chances of admission by posting your actual stats, meaning your scores on standardized tests, your GPA and class rank (and from what sort of high school), your extracurricular activities, and your awards. In general, students accepted from abroad to top US schools with full financial aid awards are the top students in their countries.
