Great to hear you interest in Math and Statistics.
Math and Statistics are being used more and more in diverse industries as amount of data being generated is growing - mostly produced by machines (web servers, telemetry, sensor data, Financial instrument etc). Given the voluminous nature of this data, there are big challenges to analyze it. That is where statistics and machine learning comes into play - to find meaning and patterns, followed by data driven decisions.
Once you have completed your education in these areas (mostly a Masters and/or PhD is required), you can work as a Data Scientist in a tech company, as an investment banker, a bio-statistician or even an economist.
Hope this helps and Good luck!
