No: there are many private (and public) universities that would be happy to have you. Overall, you have great stats, but you are considering applying, as an international student, to some very competitive schools in a very competitive subject (which happens to be strongly linked to math, your least strong IB prediction), and you are not accepting the general feedback that your assessment of what is a reach/match/likely for you is overly optimistic.
The posters here really do know what they are talking about- and they are genuinely trying to help you: they want you to have good choices come next spring. Most of them have been doing this for a long time- and they do it because they want to help students be successful.
ps, it does sound as if a BA CompSci might suit you
