A beginner’s dilemma

The title accurately describes my situation . I am in interested in web development , the UI of applications , the backend processes handling loads of data and data analytics because deriving a conclusion using huge amounts of data , creating predictive models seems fun and has my interest. I have started with web development as of now . I know HTML and Dart and I am currently learning python and CSS because I am having a lot of free time . So , how can I find my path ? Considering the fact that I am going to enter the workforce probably after 4-5 years , in which niche should I invest my time in ? ( I am from India and just cleared 12th grade exams).
