Stock Market Risk

Since I've started playing blackjack (about twice a year since 2022) I've noticed I'm taking more risk in the stock market. I've never been a mutal fund guy (unless you count brka/b) and always held 10-15 stocks across all my accounts. However, ever since I've taken on blackjack with it's thin margin, when I fall back to the market with it's historial 7-8% I find my self taking more risk, including my retirement accounts. I only hold 3 stocks across all my accounts and don't seem to worried. I'm sure playing blackjack is the main reason. Has anyone else experienced this?
