Ok, i'll try to answer your question if you don't want my hug then
.
I don't really think people are arrogants overall, exept when there is a stake (thinking about tournaments & stuff ), thats the type of arrogancy that will bring the desire to beat who ever was arrogant.
So the purpose of it was to hype you up.
Beside that, there is few personality that plays with the arrogancy, and structure it to belittle you, the purpose of that is to make the target raging and feeling bad, demoralizing you. You should totally ignore this one.
But overall, if you act nice and got an open mind, you should be able to talk with alot of players without being rejected, or badly considered.
