Although he had pride and great confidence, Raven never believed himself to be an arrogant person nor did he allow cockiness to grow over his head for more than a few seconds when it arose.
In fact, because of his cursed luck, what he had learned throughout his life was that no matter what happens, he must never allow himself to get full of arrogance or karma will teach him a great lesson fairly soon.
For instance, there was that time in the past when, through Lady Luck's massive blessing, he won several grand just under a single night. He became so happy or could be said cocky, that he began to mock those who lost, only to be beaten up and get robbed the very second he left the building...
Even right now, if Raven thought back about that moment, he felt both shame and anger for being so ridiculously stupid!
