Did he get into Stern, or into Tisch? International level theater activities could get an applicant accepted to Tisch with those GPAs, especially if they were applying to performing arts and did not require standardized testing. However, I would be very surprised if your friend was accepted into Stern with that GPA and those standardized test scores.
Your presentation at 2030 could have pushed you over the finish line, had your grades and SATs also been stellar. You are competing against international applicants who have similar national and international level recognition, AND have GPAs over 90% and SATs over 1500.
Is it possible that you will be accepted? Maybe. Is it likely? No.
However, even before all of this: can your parents afford full tuition, or even partial tuition at NYU? If not, you may not even be accepted, since NYU is need aware for international students. Even if you are accepted, NYU is expensive, and they are not very good at financial aid.
