Xuzhi,
UChicago prepares our students to enter roles other than trading and quant trader; our graduates also obtain positions in risk management, consulting, data analytics, and quantitative research and analysis. As a suggestion, perhaps you should defer a year and work in the industry to understand what technical skills you will need to have and to build your network. Please note, while it's okay to enter these programs with some career confusion, you seem a bit all over the place and that means it will take you longer to realize what you "do not" want to do.
