What does this quote actually mean?

"This was driven mainly by Microsoft’s Xbox One, though Sony’s PlayStation 4 remains the best-selling console in March and 2018. The Nintendo Switch 32GB with red and blue Joycon controllers was the best-selling hardware in March and 2018."

Switch sold more units or what?
