I don't think its meant to convey an emotion. Its just an 8-ball.

See here.

So, like when i need to win something? Or lose i suppose if it's too early

I remember 30-40 years ago when they had an "8 Ball" which was supposed to answer questions. You shook it and the interior ball which floated in some fluid would revolve a printed answer to the window.

I had one too. I remember using a real 8 ball I drilled out in wood shop and used it for the gearshift knob on my '67 Firebird 4 on the floor convertible ;-}
