When google says 50k - 100k they mean impressions. This means that people have typed in the keyword in google that many times. They can do all kinds of things after that search. Some might just search for something else and not click. Some only click on the first 3 results. Some only click on the adwords ads. Some only click on the first result. A very small portion are going to click past position 3.

When people type in a general term there is a very good chance they are not going to hang out there. They will find out very quickly that what they typed in was too general and will type in a more specific term.

One thing you can do is go to your keyword list in Google analytics and go to the bottom you will see a pull down box that says "containing". In the box next to that type in your root phrase. This will give you a list of all the terms that were typed in using that phrase.

A general term is sometimes called a head phrase. Most people that type this in are browsing. People start off general and get more specific. When they are ready to buy that start typing in very specific search terms that are longer and these are called long tail terms.
