Keyword ranking high but not getting much traffic

[AidanSEo]

A kw is ranked pretty well in the SERP's it basically varies from 7-10 top positions.

The search volume is in thousands. But how cam the kw actually gets only a handful of traffic (200-360 or so) per month. Not even per day. Its showing in the first page then why so much difference?

The "in the thousands" volume is typically per month.
Also, keep in mind, that organic position #1 receives around 24% of the clicks, and falls off to nearly 1% after position #3.
You won't be seeing a lot of that traffic in position 7-10, so work on improving your rank!
