Webalizer statistics get generated in the folder 'stats' of each website. So if you have created a new website mydomain.tld, then webalizer statistics are under https://mydomain.tld/stats/ And be aware that they get created nightly, so if you add a new site, then it can take up to 24 hours until you can access the statistics the first time.
Is there a reason why Webalizer is used? It is quiet outdated, unmaintained (except a few more recent build fixes) and the generated stats are inaccurate. You are better off using AWStats or GoAccess as stats generator.
