There are a lot of areas where computer scientists can work, and it's worth exploring the things that interest you the most to find which one feels right for you. There are two sides to computer science: the theoretical and the practical. Much like how studying physics can end prepare you for a career as a theoretical physicist or an engineer, computer science can prepare you for both theory and practice. Most jobs involve both, but will generally have a higher concentration of one over the other. For instance, jobs such as software engineering involve a lot of practical concerns: technical knowledge of programming languages, how to efficiently build software for other people, and effective communication. But having a solid understanding of theory allows developers to select the most appropriate algorithm to efficiently process/store data.
On the theory-heavy side, there are things like artificial intelligence, machine learning, data science, and high-performance or scientific computing. These all involve practical concerns of writing good code, but they rely on a solid foundation of theoretical knowledge of mathematics, statistics, and computer science like algorithms and data structures.
