I am not sure what casino owners think about the lightning networks. But, If they implement it, They also have to keep the main network on. Because only a few percent of players will understand what is lightning network and how to use it. But, yeah. If the platform implements the lightning network that I am using, I will use the lightning network since it's fast and cheap.
I don't think the lightening network is generally accepted by everyone because not everybody understand the concept of it although there are claims that it helps to reduce the network free and makes transactions faster than normal. The lightening network will limited gamblers maybe casinos owners in knowing the actual portfolio they have cause the transactions that are used through lightening network do not go to the wallet directly.I think that the fact that people do not fully understand the underlying technology, the use itself as user is not that difficult. Just take example of the regular bitcoin network - it is a very complex system with economic, software, hardware and many other sub-systems logical ans physical involved, and yet making a transaction is as easy as a couple of clicks. Complexity is not much of a problem.
Yes it is not that hard after some experimentations with small amount and reading article or youtube online you will easily understand how it works and you have to try it by yourself but I think many people doesn't have time to test it that's why until now they are still afraid of using the lighting network.
