Are bitcoin bets and payouts transactions on the block chain?
When you deposit and withdraw to and from a bitcoin dice site those transaction are on the blockchain. Everything in between, like your bets and payouts, is just being recorded by the site not on the blockchain.
As such your balance is not 100% in your control until you withdraw it back to your own wallet on the blockchain.
