Do nofollow attributes stay when I delete plugin?

I’ve recently switched over to the Gutenberg editor and would like to delete the Ultimate No Follow Plugin. I’m wondering what to expect when I do so. Are all of the attributes that are added via the plugin (nofollow) permanent or will they disappear when I delete the plugin?

Similarly, will either the noreferrer or noopener attributes be added to all of my links when I delete the plugin?

Thanks
