Please help me understand the difference between these two screens.

Thank you for responding. I did that, but it still doesn't have the same heading set up. Such as the circle with the three dots where I can easily add a new folder.

It won't and can't. One is a Finder window (Finder is an app, technically), the other is a dialog box for opening a file. The function of the latter is to enable you to find a file to open.

In the Chrome dialog box, click the grouping button and set it to None (you have it set to Date Last Opened.

You can switch to Finder to get the view you prefer while Chrome is still displaying its 'Open' dialog box. But the Open dialog box called from inside an App does not have all the same features as full Finder.

You are opening a file with Chrome, it would make no sense to create a new folder when it is simply asking you which file you want to open.

If you were saving a file, then you would have the option to create a folder, as it would then make sense to save the file in that new folder.

is there a particular feature you MUST have while inside that dialog-box?

For example, there are ways to do navigation to a different directory or drive, but they may not be the ones you use daily in Finder.
