Have read around somewhat but still cannot fathom what Google is trying to tell me in the 'Keyword Ideas' section...

e.g.

If I put in my keyword as golf then I get the following report:

golf.jpg

Is it really saying that I should expect zero click thrus (per day) from the huge amount of 4,090,000 monthly searches if I use the phrase "golf clubs" and have an estimated ad position of 4.75?

Likewise, can I also expect zero click thrus (per day) from the 368,000 searches if I use the exact phrase [golf clubs] with an estimated ad position of 7.16?

What am I misunderstanding?

Thanks for any advice.
