Safari virus

So I was on urban dictionary just for fun today, and I randomly got a pop up saying “Congratulations loyal user you’ve won a 1000$ gift card” or something like that. I screenshotted just to be safe and without clicking on anything, I got redirected to this weird page and got a red screen with a triangle saying malicious page or something. I checked my safari settings and popups are properly blocked. I cleared the data and nothing happened but I am still suspicious for it.
