Debating whether or not to keep or move Money Market Funds into high yield savings account

Let me start off by saying I don’t know much about how economies work. I just know that my money is best served not being in a place where I can spend it so I’ve been investing in ETFs and sending around 15-20% of my checks into a Money Market account for future big purchases (house renovations and such). However, the current US economic climate has been so volatile lately and, since I don’t really know what a Money Market really does or is, I’m not sure if it’s entirely safe at the moment. Would a HYSA essentially be the same level of risk in the current climate? If both are the same, is there something else I could be doing? Thanks for the replies and suggestions!
