Is It Possible? Non traditional background

Hi. So I know that it is uncommon but I decided to go back to university in hopes of making into IB or S&T. I'm 27 at the current moment and will be 30 by the time I get my degree in math/ finance from a european university. I stopped going to school because I worked in a funeral home and became the MD. That helped me to get confidence in talking to customers and to get strong in sales. I also handled all the arrangements for burial and funeral services of the deceased, in accordance with the family's wishes. I performed a wide variety of duties, such as planning and allocating the resources of the funeral home, managing staff, and handling marketing and public relations. I gained knowledge of financial statements, accounting. I've always wanted to be a banker or investor but I got side tracked and was wondering if it is still possible to break into it after I graduate? What job would suit me? Which division could be a good fit?
