What do you mean by playing games through the cloud?

For example, when I say a person is a cloud player, I mean that person only watches videos of anchors and masters on the Internet, and then thinks that he has rich knowledge and good skills, so he can play in various and He talks nonsense about games, but in fact he has not cleared the level at all and may not have even touched the game. Cloud leveling relies on watching the anchor's leveling video online or completing the level in his own imagination and YY. There is no actual combat.
