If you were a domestic student, I’d say you have as good a chance as any for these schools. But these schools are major reaches for ANYONE, especially international students. You’re also coming from a country with lots of applicants, which makes it even harder. So unless you did some life-changing work or are one of the top students in the country, it’ll be near impossible for you to get in.
There’s also the issue of finances. Can you afford to pay full price for a US school? Few US schools give aid to international students.
