22, Nervous about Risks / ETF vs Individual Stocks

I’m 22 and currently have around $15k invested, mostly in VOO and QQQM. I contribute consistently and plan on holding long term. I keep hearing people say that if you want to become seriously wealthy, you need to pick individual stocks and that ETFs won’t get you there. I understand individual stocks have more upside, but I also don’t want to take unnecessary risk trying to find the “next NVIDIA” and potentially lose a large amount of money. For people who have been investing for a long time, did you stick primarily with index funds or eventually add individual stocks? If you did add them, what percentage of your portfolio did you allocate to them? I’m not looking to get rich overnight. I’m mainly wondering whether I’m being too conservative by sticking with VOO/QQQM at my age.
