SEO equals subdomain, wildcard, fake subdomain, and GOOGLE'S ATTITUDE!

[Chrism13]

Good evening... I wanted to consult with you about a VERY STRATEGIC SUBJECT... A manually created subdomain is considered as a separate domain by Google and starts from scratch in terms of SEO. Here are my questions: 1) I believe the same situation applies for subdomains created with a wildcard. Do you think Google also evaluates these types of subdomains as separate sites? 2) For creating a wildcard subdomain, is it sufficient to have the DNS record of *.domain.com + htaccess configuration, or is there an additional step? 3) Is a fake subdomain a different method from a wildcard? If it's a different method, what is the difference? Does Google evaluate these types of subdomains as separate sites? 4) Apart from these, are there any other methods for creating a subdomain? If so (which I doubt...), does Google evaluate these types of subdomains as separate sites? Thank you very much in advance...
