I remember back in my childhood in my teens at the beginning of these 2000s I taught myself HTML in less than 24 hours. I was wondering if it were possible with JSON and XML.

What you taught yourself in less than 24 hours then was the basics of html. You got better at it as you kept using it and you keep discovering new things. Its possible that you are still discovering new things in this fundamental language up till now.
In the same way you can get the basics of XML (whose subset a beginner can say html is) and get better at it as you keep using it. The same goes for JSON which is more of a data structure just like XML.
But it all depends on how fast you can learn which your claim shows you are. Though one can only wonder why you will learnt html at the beginning 2000s and have not know this 2 fundamental languages.

Why learn both though ? And why do you want to learn them in a Day (who dey pursue you) ? I mean, JSON was born out of the need to eliminate some of the disadvantages that are encountered in XML for serilization of data.
for example using Javascript and depending on the parser:
A typical json would look like this:

someJSON = {
          "title" : "Return of the mark",
          "length" : 243
}

while the XML equivalent will be this

<song>
    <title>Return of the mark</age>
    <length>243</length>
</song>

The JSON will be parsed like this:

song = JSON.parse(someJSON);
console.log(song.age);
console.log(song.name);

while the XML will be parsed like this:

someObject = parseXML();
songs = myObject.getChildren("song";
song = song[0];
console.log(song.getChildren("title"[0].value());
console.log(song.getChildren("length"[0].value())

It's obvious which is fatter right ? That's why JSON is often referred to as fat-free XML.

That said, both XML and HTML are derivatives of the Standard Generalized Markup Language (SGML). However, compared to SGML XML is simpler while HTML is the simplest of them. If the reason you need XML and JSON is for data-interchange then learn JSON first has it is starting to become the de facto standard for serialization of data and that's why every major website this days including social networks have a RESTful API.

JSON replacing XML for data-interchange doesn't mean XML will become useless with time. XML in itself has many other derivatives and it is adopted in many programming languages and frameworks for example Java uses an XML derivative called FXML for JavaFX, .Net uses XAML for Windows Presentation Foundation (WPF) and Spring Framework uses XML for may of it's plumbings. When you can you should learn XML in case might have a use for it in the future.

The reason I never spent time learning XML and Json is because I'm not currently involved in Web Development. I'm in the Network Technologies and Engineering realm. But I'm interested in improving myself in another area of I.T.

Good stuff, Json definitely seems like the better language whereas XML like HTML is a markup language. So I see your point.

JSON is not a language.
It is a data structure, so there's no learning to it. No body writes JSON data, it is generated and parsed by a library.

There's also no learning to XML. It is a custom tagged markup language.

Cool got thank you for the information
