Am I a dual status alien?

I was a tax resident for the year 2018 on an F1 visa. I left the US on January 24, 2019. As such, I believe I was a tax resident at the beginning of 2019. I then visited the US for 13 more days in November 2019; and therefore I pass the substantial presence test for 2019.

Does passing the substantial presence test for 2019 mean that I am a tax resident for the entire tax year of 2019? Or does this mean that I am a dual status taxpayer (since I no longer have a residence in the US by the end of 2019)?
