Finding Better Keyword. Can You Help Me?

At the moment, im on the process of keyword hunting to start my next topic on my newly created website, as this is my first time to focus on low competition keywords to rank on search engines, i just want to ask some question regarding this. After Doing some keyword research on "LongTail Pro" and selected those keywords with just 100-500 searches on local / United States, then i analyze those keywords on Moz Keyword Difficulty and this is the result, the screenshot below, and most of them have 20-70% keyword difficulty.. are those keyword easy to rank if i depend on the percentage of it? . please help me with this.. thanks (sorry for bad english ^_^ )
