3Blue1Brown on YouTube has a number of great videos into math that help give a visual understanding without needing to sit down and do the pure number crunching. I'm not sure he has one on the Riemann Hypothesis in particular, but he does cover a number of items that would be somewhat related and help build a level of comfort with being exposed to the math, even if you can't do the pure number crunching. Mathologer would be my second recommendation. Once again not sure he has touched the Riemann Hypothesis, but he does a number of great videos where you can start expanding being comfortable with often untouched fields of math (like modular arithematic) while introducing a how seemingly unrelated fields end up having connections. Videos can go between 20 minutes to an hour and I often enjoy watching one every few days.
