what are RCA exactly? are those the white and yellow audio video cables that are on most electronics?

and in that link you provide what is that green plug beside the S video?

S video is to connect Computer's S video output to S-Video input of a TV.

The two RCA are for Right and Left Stereo Audio to plug to the TV, the little green card is the stereo Audio from a computer's Audio Output.

The cable that you link to on NewEgg has RCA on both sides. I.e it is for a device that its Audio Output is two channels RCA.

If you only have S-Video on your computer and only have Composite Video on your TV, you are going to need a conversion device. There are S-Video to Composite Video adapters available, such as the cable mentioned earlier. The only such converter I ever tried came with a higher-end video card I had from years ago. The end result with a newer video card was that I lost all color on the TV. Great B&W video, though.

You may want to find an inexpensive video card that has a Composite Video output.

Here's two cards from Newegg.com:
Composite Out

And here's fourteen cards with both S-Video and Composite output:
S-Video plus Composite Video

You can also convert S-Video to RF (Channel 3 or 4), but my experience with those converters over the years has been awful.

The cable you linked to can connect an S-video output from your computer to an S-video input on your TV. But you don't have one! So no, this won't work. You need either:
(a) a different TV with a S-video input;
(b) a different video output on your computer, called "Composite Video", and a different cable with RCA connectors on all three lines; or,
(c) a converter to make Composite Video from an S-Video signal.
The better of the lot might be a different computer video card with Composite Video output available.

Here's the color coding convention on RCA cables:
Yellow is Composite Video
White is Audio Left (Stereo) or the only audio if it's mono
Red is Audio Right
In your case to make stereo audio output fit into a mono input on the old TV, you can do:
(a) White to White - your TV will get only the Left channel of the Stereo signals, but you can ignore that.
(b) White to White and then, in the computer's audio card properties, find a control which converts any stereo signal into mono output on the Left (White) connector only. Then your TV will get both channels mixed together on one mono line.
(c) Get a 2-to-1 RCA splitter with two female connectors for the white and red lines coming from the computer, and a single male output connector to plug into the TV. This will effectively connect the Left and Right audio signals together in parallel and feed them both into the TV.

I tried connecting my Svideo computer to a tv with a cable that had Svid on one end, and the composite (red/white/yellow) on the other end. It didn't work. Someone said something about the computer can only talk to the tv if it's svideo, the computer can't detect the monitor if it's composite.
