Needle valve doesn't close
I am a newbie at this. Attached is a picture of the needle valve set-up that I found in my recently purchased house:

It controls the water flow into my pool. The problem is that even when I close the valve all the way, the water continues to run through that plastic pipe. I need to stop that water flow. Is that valve broken or valves like that are not designed to shut off the water all the way? I found online that needle valves are not designed to work with plastic tubing. What do you suggest I should do be able to shut off the water that runs through that plastic tube?

That's called a saddle valve. They are absolute crap. That valve is installed by bolting on the pipe and the center pin punctures the pipe which means when you remove it there will be a hole in the pipe.
It would be a good idea to replace that with a brass ball valve.

Those saddle valves are notoriously unreliable for turning off after a few years. Many locales no longer allow them - though they are still used often.
While Pete's suggestion of a proper valve is the best solution, in a pinch, you could just cap the end of the plastic pipe with a valve. Something like this could work:
