Does this email from Google mean my account might get hacked?

I have been getting numerous emails from Google, saying that someone from different places around the world tried to get into my account through a less secure app. I changed my password two times already, set up recovery methods and revoked access to all third party apps, but I still keep getting these emails. The thing might be that I have my email on Instagram as some kind of "contact method" because I use business account. What can I do?

by the way the email is not exactly screenshot of mine, it's donwloaded because mine wasn't in English ;-;
