Prolactinomas, especially tiny ones, are super common. They often find them during autopsies. Most people with them experience no symptoms.

Are these deadly?

Not intrinsically or commonly deadly. https://www.hopkinsmedicine.org/health/conditions-and-diseas... says "1 in 10 people will develop a pituitary adenoma in their lifetime" - pituitary adenomas is the more general class of these benign tumors, as the pituitary gland produces multiple hormones.

1 in 10 sounds really common though, that's shocking.
