Do links to other websites harm my Google ranking?

Apparently Google changed their approach to the rel="nofollow" tag attribute effective 1 March 2020.

I have not changed the way that I use nofollow. I started adding it to all of my outbound links a long time ago. As this website is not a blog and has no User Generated Content or "Sponsored" content, the other combinations of the rel values.
