The Sun is a star, but not all stars are the Sun.
The Sun is a star, but the term Sun is a proper noun reserved specifically for the star at the center of our solar system. A star is a general scientific category for any massive, self-luminous celestial body of gas that generates energy through nuclear fusion. Because the Sun is just one of billions of stars in the universe, it is accurate to say that all suns (if referring to our Sun) are stars, but not all stars are the Sun.
