If you want to know more, go to https://haveibeenpwned.com/ and enter you e-mail. They maybe know, where your data came from.
Otherwise: Do you have a different and random password for each site?
If yes, change your gmail password (in as it was gmail itself) and then watch the news, if a site you use was hacked.
If you don’t have different password for each site… Well then you are gonna have a fun day changing all you passwords to new ones. And use a password manager and a new random password for each site this time, please.
