Katniss - Pool Shark?

From Katniss:

Someone told me, "I heard you are a pool shark."

I looked around and asked, "Are you talking to me?" 

He said, "Yes," 

I said, "No I’m not." 

He replied, "Well everyone is telling me you are."

I was persistent with my 'no,' even though I ran out and beat him.

My thought process was this:

A pool shark is someone who engage in sharking in billiards, that a player who distracts an opponent by means of vocalizing (talking crap) or with movement on purpose. Or a person who hustles people for money. 

His thought process was:

A pool shark refers to a player who is very well skilled. 

He explained to me that I played very well...not only against him, but in all of my games. I told him thank you 

So MAYBE I am a pool shark after all!
