Are ETFs riskier than funds?

Hello, I've been hearing a lot about ETFs and funds, but I'm still a bit confused about the risks involved. Could you please clarify for me if ETFs are inherently more risky than funds? I've read that ETFs are traded like stocks, so does that mean they're more volatile? Also, how do the fees and expenses associated with ETFs compare to those of traditional funds? I'm trying to make a decision about where to invest my money, and understanding the risks is crucial. Thank you for your help!
