They will talk about this and other things that they don't like, but gambling will be regulated by laws, not religion, so they definitely won't be able to exert any influence without a legislative base. Honestly, I haven't heard that religion could somehow influence any spheres, they can discuss this with their parishioners, but their influence will be limited by this, especially since casinos will create large revenues for the treasury in the form of taxes and this will also be important for the state.
