I put 50 cents through by accident then resent 500 dollars to the same address. First transaction went through. Second did not.

Actually, it looks like you first sent 0.000509 BTC (about 0.39 USD at the current GDAX exchange rate). Then about four and a half minutes later you sent 0.00066888 BTC (about 0.51 USD at the current GDAX exchange rate). Then about a minute and ten seconds later you sent 0.507 BTC (about 388.24 USD at the current GDAX exchange rate).
All three of these transactions have confirmed, so the gambling site HAS received your 0.50817788 BTC (about $389.14 USD at the current GDAX exchange rate). Now it is up to them to update your account balance on their site. At this point the ONLY people that can help you are the people at the gambling website. They have the bitcoins. They have your account information. They are the ones that are failing to update your account balance in their system.
