The fact being this forum is dedicated to live games, which I've tried several times previously to point out more subtly to you!.

they are the same who use them
No, not everyone who plays live dealer games gamble on RNG.


Further to which,

they are the same who developps RNG and live games
this is also not true. Many casinos have a variety of live dealer games & RNG from several providers. Such as Evolution Gaming only provide live dealer games. Even 'Playtech casinos' who traditionally just had Playtech RNG more frequently nowadays also have RNG not from Playtech.
