Just to add to the definitions that others have already mentioned, simply because a website is using an HTTPS connection does not mean that it’s necessarily a trustworthy website. The website you are accessing could be compromised, so don’t take the green lock / whatever your browser uses as the HTTPS indicator as a guarantee for security!
Another fun fact, although HTTP(S) is used for serving HTML webpages, there are other protocols for different use cases. For example, FTP is used for file sharing, and SMTP is for email. You might have also heard of the Tor network, which is used when anonymity is important (see journalists, activists, etc.)
