Keyword domains good for SEO

Do keyword domains bring up your position for that keyword?

Greetings
Sorry if I am asking a brainless question is because I am new at this
I have some keyword domains that have ok search on google. My question is this. If I build a simple site with basic seo skills, would I get to top 10 position in that keyword that I have on the domain name.

I thank every one for all the good tips.

I wish it was that easy. ;)

I have some keyword domains that have ok search on google.

Can you explain further what you mean by this? Are there already websites on these domains?
