So far there have been very few problems with licensed casino payouts and deposit security. Many of the jurisdictions require that the licensee post bonds of cash or insurance as part of the license requirements.
Your personal security (including credit card details and other personal information) should also be guaranteed under license agreements. Most casinos and sports books use secure servers to conduct all of their transactions, and all information about you is held offline. Many also take out insurance against fraud.
