Chances of getting Covid?

December 25th- I saw my MIL- she had no Covid symptoms

December 28th- I saw my parents- for about 20 mins, they are both vaccinated, and boosted. I am also vaccinated, but not boosted. The visit was super short, but we did hug hello.

December 30th- my MIL tested positive for Covid

What are the chances of me giving Covid to my parents?
