Ironically that was the cause of the first worst scam calls. The govt had a do not call list that you could put your number on which then became THE phone book for scam calls instead of stopping them. If you’ve ever signed up for anything or paid for anything online and had to give your phone number, it went into a list that was sold on. With auto dialers, they just go through every permeation of possible numbers. I don’t get many calls on my cell because I keep that number private and use my already compromised land line for everything.
