Statistics theories play a decisive role in data science. Statisticians collect and analyze small amounts of data, usually through traditional methods. On the other hand, data scientists gather large amounts of unstructured and structured data and interpret it with different tools. Without statistical research, there is no data science. It represents a solid basis for its more complex areas, providing methods for data structuring for further analysis. In a way, data science evolved from statistics and is still relying heavily on it. However, at the same time, it is also expanding into various other fields.
