n/a Keyword difficulty but high CPC

Im not quite sure where to post this, so im gonna post here.
I have found keyword that have n/a keyword difficulty with global volume 480, and CPC is pretty high (22$). Im not sure what to think about this, is this hard to rank with only good seo (on and off page) without PPC? Can someone explain me this, it doesn't make sense to me.

Better than just following the keyword difficulty, why don't you research each of the links at the top of the SERPs individually?
Maybe you find that they are highly competitive and you figure out that $22 CPC

log out of your google account, connect to a USA IP via a VPN, type the keyword into google and check what pages rank on google's 1st page. If you only see known / popular / big brands in the niche of the keyword you're fucked! If you see sites like reddit, quora, stackoverflow... or forums... it's a good keyword and you should create content for it ASAP

Of course, this is a simplification and you will most likely only see tough sites (big brands, high DR, tons of RDs, etc) ranking on 1st page of google, in which case you should run a deeper analysis of those top 10 pages to check their backlinks and content a bit more because you might still have a chance to rank for that keyword. But... knowing google's addiction to authority and trust (and censorship and manipulation, but shhhh!) you will probably only see big names ranking for that keyword and have no chance whatsoever. But still check it, just to make sure. It's better to know that you have no chance than assuming you have no chance and realizing later on that you've been wrong

@SirLouen @tazarbm Thanks very much for fast answers, you're both right. Big names in that niche, high DA and a lot of traffic. So yeah, that KW is too much for me right now. Thanks again for fast answers.
