Yup, you were filtered out by Stanford, I think.
Your profile was a match for UChicago TO, so you were lucky. I’m thinking other elites would have acted more like Stanford, than UChicago too… Even UCLA’s, though an acceptance, was a bit bland… considering that they know that you will need huge financial support, but did not offer it. (or maybe they made theire best effort but due to budget issues…)
Good luck on UChicago. Dont look back. And if you are planning for grad school, make sure to test high on the LSTA/GMAT/GRE because getting those numbers up will be even more important. There are no “test optional” elite grad schools.
Congratulations.
