From experience it seems to be semi-random.
I've never had a single spam call on my main phone number, but friends who have got a new number get maybe 20 spam calls per day, with only having given their number to their closest friends and family.
I think one factor that weighs in heavily is if your contacts download thousands of spam apps onto their phones and click YES to every permission. Then your phone number is harvested from your contact's phone and sold. TikTok, for instance, will beg me multiple times on a frequent basis to see my contacts. I don't think you can even install WhatsApp without giving it your entire phone book, can you?

You can. It will cry and beg and nag every chance it gets (same as when you don’t allow notifications) but it will still function without these permissions (for now).
Tested with WA business on a “landline” voip number because I don’t want people to contact me via WA (and they would if I used my cell number for WA)
