That is mostly true—many of the products that contain it count as having it encapsulated, so you can leave asbestos tile on a slab and cover it with another material. However if you go to demo the tile, and start hitting it with hammer drills etc. as a frangible material it can become aerosolized and be inhaled in the lungs, where you get the horrible health effects, so you have to follow remediation protocols to do that. Obviously hitting those types of materials with explosives is going to virtually guarantee try st it gets airborne.
That said there were many applications of asbestos, like old wrapped pipe insulation for instance, where the asbestos is already in a spun (think like fiberglass or rock wool) format, and those types of things need to be remediated just for existing as they are hazardous and can leach particles into your environment easily.
