New to stock market (looking for advice)

I currently just made an ira account with Fidelity. I started with 170$ and brought 15 shares of a stock named ASMB and made about 5% interest so far. I now have about 193.50. How does the stock market work? Also how does compound interest work? Would I gain compound interest for having shares of a stock? Or do I have to invest to get interest on my money? I'm currently trying to put 50$ a week into my account. Please give me advise. I'd like to also know would it be stupid to buy shares of a stock instead of saving my money to just invest in something like s&p 500

I do not want to pretend as if I know the first thing about smart investments but I know the facts is I have 193.5 and I'd like to make smart choices and I need everyone here's help thank you in advance :)
