Timeline time units. I want smaller units

Compare with Audacity and zoom in. You can zoom in to a tiny time unit. I guess I can move on the timeline 1/1000 of a second with the arrow keys. As far as I see CS 2018 works with 30 units per second, must be 30 frames per second.

Or did I miss something ?

Audio editors are unrestricted by time constraints. Whereas Video editors are restricted by the frame per second of media or project.

Video editors edit in Frames Per Second. Camtasia 2018 is capable of editing at 30 or 60 frames per second.
So, time wise. 60 time units/per second is as small/incremental as it gets.
So the timeline only zooms into 60 frames per second.On my 23" 1920x1080 monitor. A 60fps video timeline fully zoomed in.Displays 3 seconds of video from the far left of the monitor to the right.

Because video editors produce video in fps.They must handle the audio in fps as well.
You could edit the video in a program like Adobes After Effects at 960 frames per second.
That could get you to 1/960 of a second granular control. Very close to 1/1000 of a second.

At 960 fps. I doubt any of this is a practical approach or solution under any circumstances.I've never heard of anyone actually attempting or doing this.

Its just the best way I could think of at the moment. To demonstrate the difference between video and audio editors.

Actually, you missed one thing.  Camtasia v8.6 for example will edit in 1/30 of a second increments (due to video editing, as Joe noted).  But to be 1000x "worse" than Audacity it would have to edit in increments of 1 second, which would be bizarrely inaccurate.
You would be more accurate if you said Camtasia v8.6 was around 1/30 as granular as Audacity (1/30 of a second vs around 1/900 of a second).  For Camtasia 2018 working in 60fps mode, this would be 1/15 as accurate as Audacity -- not 1/1000.
Anyway, on those occasions when I find that this imprecision is frustrating my efforts to remove an extremely small sliver of audio, I dump the section of audio out as a WAV file, open in Audacity, replace that tiny fraction with silence, and save the result as an edited WAV file.  When I import the edited file into Camtasia the sliver is silent.
No matter what, though, you won't be able to edit the video to that same tiny degree (which is why you want silence replacing that sliver of offending audio).

Like Michael, I like zooming way in on the audio time line to remove or enhance tiny imperfections. I do that often in Audacity and Audition and then export and import into Camtasia. But I also really like and miss the workflow between Adobe Premiere for example and Audition, where you can select "Edit in Audition" on any part of the audio track and perform such minute adjustments.

However, I don't always have the need or the time to be so precise. In such cases, I have done some amazing things working with 1/30th of a second in Camtasia to clean up noise or tighten gaps. In short, if I am in a hurry, I can do rough work in the Camtasia audio editor. If I need to invest extra time to get the audio perfect, I don't mind re-editing in Audacity and then re-importing the audio track to Camtasia. I've streamlined the workflow so it takes no more than an extra minute or so.
