Hi monparsons,
I would love it if you could see yourself a someone who learns and has maybe not received the information needed.
Please attach a project file if possible, for future questions, thank! Images have not a lot of information. I can see the problem, which is excellent, but typically I can’t tell you precisely what the next step would be. Perhaps here I might guess correctly…
I found over the decades that guessing is a waste of anyone’s time. It will work or not. A project file is a piece of clear and stable information.
Please open the attached file and have a look at how these objects change. It is a question of segments. If you set the Capsule to the same number as the Torus, then it should already look much better.

The key is to find the sweet spot between the number of segments and the needed smoothness. In other words, to just increase the segments will slow down anything, which is not very useful.
I hope that supports your progress with this tutorial.
All the best, stay safe, stay healthy.
