Hello,
the difference is quite simple, I'd say. Casino A is licensed under the Maltian gaming license - which is highly recommended. This means that casino A must fulfill all the necessary requirements to even get the license and it's also accountable to this authority. Frankly, lots of players do not care much about safety or don't want to bother with a full verification before their first spin for example...
Now, casino B operates under no license at all. No requirements, no restrictions no worries - until some issues arise. There is no authority (except for local justice) you could directly ask for an investigation and turn there for help. Plus such a casino does not care about its reputation so no leverage can be used against it.
Setting up an online casino without a license is like making an e-shop, I'd say.
It's always up to the player to choose where to play. Hence, we're constantly trying to provide players with all the information relevant to the casino's fairness. The license matters so we warn:

"If a casino stubbornly refuses to pay you your legitimate winnings, the only possibility that remains is to turn to the regulator who issued the license to the casino. Only then will it show how important it was to choose a casino according to who issued their licence. A good regulator should always stand independently on the side of fair gambling. He should fairly assess and investigate every official complaint. In case of a serious violation of the rules by a casino, it may accede to revoke their licence."
