Firstly, it states that "a data scientist uses compact languages such as SQL and R". It doesn't state "everyone who uses SQL is a data scientist". That said, the term data scientist itself is a bit frustrating. It gets thrown around a lot as if it is a well-defined role, and it is anything but. In my experience, the role of a "data scientist" is about as well defined as the role of an "engineer": it has connotations about the type of work and maybe a few shared skills, but the specifics of what an "engineer" does and their skillset varies widely depending on if they are a software engineer, an electrical engineer, or a civil engineer. So while I think that most data scientists know SQL or use SQL frequently, I don't think that all data scientists use it, nor do I think that everyone who uses SQL works in a role that would probably be considered that of a data scientist.
