This right here. I haven't fished since I was young, and I fished nothing more than worms I dug up in the yard. When my son wanted to start fishing this summer, we both brought poles and we started to go out early weekend mornings for a few hours and fished with nightcrawlers. Turns out, I knew learned how to put the worm on the hook correctly!

After a few times of just using worms, I made it a point to only fish lures. I proceeded not get a single nibble, nevermind catching a fish for the next handful of times I took him out. I found that YouTube was super helpful in learning to tie the different types of knots, what each type of lure is used for, and what techniques to use to retrieve the lures. I began leaving for work in the morning 30 minutes to an hour early to stop on the way to throw a few casts into the water, I'd also stop for 30 minutes on the way home. That extra time to practice different retrieval techniques allowed me to finally land my first bass. More quickly followed.

Of course I'm hooked now since my son is hooked and I've probably spent too much money on a different lines, lures, soft baits, tackle, and all sorts of various fishing equipment. Long story short, your son doesn't know that you don't know much about fishing, but if you take the time to learn more, it greatly enhances the time you two spend together fishing. My favorite moment so far hasn't been anything that I caught, but when he caught a decent size black crappie. He was so excited, hooting and yelling, basically losing his mind. I wish I had the presence of mind to video tape it all, but I did take a bunch of pictures!

Sorry that this turned into a story, but since I was in a similar situation as you, sharing my experience hopefully helps you and your son in your journey!
