Speed doesn’t matter when you hit your head.

I had a friend who fell while ice skating at the speed of a slow stroll, and hit the back of his head. He was dead a week later.

And just getting a concussion can result in measurably decreased mental capabilities for months.

Dad time: you’ve got one brain for your entire life. Stop relying on luck to keep it in working order.

Permanently, not months. All concussions result in some permanent damage, some moreso than others.

But it totally does matter when you fall and smack your elbow. OP mentioned that bowl skaters are wearing no protective gear (pads/helmets), not just talking about helmets.
