Google link does not link to my website

The link to my website off of google links to an AD for an online casino instead. However, I can still get to my website by typing in the address directly, and it doesn’t seem that the content of my website has changed at all, only the outside link.

My website is the Willamette Collegian, and the url is
https://willamettecollegian.com/main/

But as I said, the problem isn’t in getting to the website directly, it’s getting to it off of google. Searching “Willamette Collegian” in google (and possibly other search engines), will bring it up as the first option.
