Nope, weight matters a lot less. Speeds are higher and speed variation is lower. Some of the best wheels are meatballs.
My partner has some Chinabron wheels. They have very basic sealed bearing hubs with meh hardware. The spokes are bladed, the rims have a channel for the tire seam, and the spoke holes are offset. They've seen years of use and some crashes and made it through just fine. There are nicer wheels out there, but not for under four hundred bucks.
