At any top school there will be a holistic review. Was the 3.7 at a school with tough grading so still in the top 10% of the class? What was the course rigor? Upward trajectory? Etc…
That said, there was an article recently from Trinity that said GPA is a better predictor of academic success. As you noted, tests can be retaken, tutors hired, etc… but GPA shows overall effort all four years.
Anecdotally, my D’s friends who had a mismatch didn’t fare as well with admission. That said, they are now doing great where they landed.
The top schools are reaches for everyone. at this point all you can do is wait and celebrate where you have already been accepted.
Good luck.
