Data Analyst question career

To become a Data Analyst I see on LinkedIn that they required SQL, Python, R. plus some visualization tools.
Can I became a Data Analyst using SQL? or Do I need to learn Python?

SQL is a language for access a database.
Python and R are programming languages.

I am not a data analyst but assume you need both SQL and Python.
Like in web development you need Javascript or PHP for the main programme but SQL or other database language for accessing a database.
