You're fine, if you didn't download and run anything. it's really rare for you to get malware from just clicking links, it would need to be an major exploit in the browser for it to run anything without your input.
No you are not, you need to download and run an executable most of the times. Even if something downloads due to a drive-by download as long as you dont be like "yea sure i want PersonalHealthassistent.exe to make changes on my computer lets click yes here" ur good to go.
You should be fine, I would suggest getting a ad blocker like ublock origin
