Ethical Hacking - Python - bypass HTTPS

Hello - I am learning ethical hacking using python, I am in section 10 - 3rd lecture. As its mentioned that these attacks will work in https websites, is it still true as of today? I am assuming that when this section was recorded (2017/2018), these https websites that Zaid is testing didnt had “HSTS” and hence it was possible to downgrade to http from https by sslstrip.

So with websites running hsts, does sslstrip still works?

There are very few websites that have HSTS vulnerability now. So mostly, this will not work. But it is a good thing to learn as once it used to work.
