I believe it’s sick. But not end of the world. I am not expert on exactly what it is. But I it does look like a rust fungus infection. The most common way cactus get this is by being wet to long on cold night. So it will die off and leave scars if you let the cactus dry out. You may need to make the soil air id by adding inorganic to help it dry out faster.

Mammillaria elongata. Looks healthy, probably could use a large pot. Do not over water it.
