They are all-but deprecated though: HTML 1.0 is much different from HTML5 (2014); XML is upgraded to XML 1.1 (2004) and most people use JSON nowadays; and ZIP is very inferior to gzip and 7-zip. We're lucky web browsers are strict with never remove compatibility for old sites, and ZIP is still used by macOS instead of .tar.gz for some reason.
Once something is mainstream and non-perishable, odds of it going away go down and it's foreseeable that it will be around for at least as long as it's already been around.
This effect is super strong in tech, for base technologies, with lots of integrations, especially around enterprise/governmental systems (which don't get changed unless someone makes a strong business case why the change makes more money) and consumer hardware (which tends to linger for aeons since it's so distributed).
Also, several other tiny insignificant Operating Systems like Android(/Linux) [apk files] and Windows [builtin explorer support]. Let's also not forget Java JAR files.
However, the threat of fubaring web media doesn't come from markup (HTML, XML, SGML) but from the complexity of CSS having gone rogue, and JS.
Or DRM. HTML still being used isn't going to help you when its wrapped up in an encrypted blob. We're not there yet (except for video) but you can bet there are plenty of actors who will jump at the chance.
I wouldn’t be surprised if some of those go out of use in a few hundred years, if not much earlier. There will probably be major conversion efforts going on at some point. The alternative, the above formats being maintained for eternity, would be somehow depressing.
