What is "order" and "disorder" in entropy?

What is "disorder" in entropy?

Entropy is measurement of "disorder". (Some says it's not "disorder")

I had read "disorder" and "order" of entropy in my book. But I was wondering what "order" and "disorder" actually represent. As Boltzmann said,

$$S=k\ln \Omega$$ Where $\Omega$ is number of microstates.

Disorder actually means lackness of order. So order means in entropy that particles move symmetrically. But particles move randomly we just can say with possibility where it is located but we can't say absolutely where it is at time 't', that's what is known as disorder, isn't it?

At the current time of the video : https://youtu.be/sPveM04XCxI?t=143

he wrote that "Energy can't be destroyed but it can created". I don't believe it but the person wrote in that video's description that "this video is specially made for the S.Y.Bsc Physics students". My mind can't agree with the statement that's why I am writing it as comment. If he is true than I will create a new question.

Where do you read that statement? I only see: “Entropy can't be destroyed but it can be created.” And while for energy that statement would clearly be false, for entropy it's true. Except in equilibrium, of course, because there the entropy is already maximal. But then, if the world as a whole were in equilibrium, there would be nobody who could do anything anyway.

Sorry! Did you misread? I said energy. But you said Entropy. There is difference. And I had read it in First law of thermodynamics.

Instead of deleting my earlier comment, I am just adding new comment. Since it's not you who misread. It's me who misread. Cause the youtuber had wrote Entropy but I read Energy. Sorry again!

No problem. Maybe I should have been more explicit that I was talking about what I see in the video. That would probably have avoided the misunderstanding.
