Diffirence between sessions and clicks on Google Analytics

I'm getting confused on the reports that I'm getting from my Google analytics account. I'm doing purely organic optimization and I'm getting good numberS of
Sessions at "2442" and users at "1722" HOWEVER for some weird reason it give me "0" number of clicks when I check on my Queries under Searh Engine Optimization.
How are these things different from each other?
Please heeeelp.
