What do the "Celestial Candou Potato, RNG, S8, G2..." that have dominated the screen recently mean?

In order to facilitate understanding, I have to start with S8:

S8 is the abbreviation for the eighth season of League of Legends. League of Legends is a popular online game in recent years. It is released almost every year. It will be scheduled for a season, and it is already the eighth season. Recently, S8 held the global finals, and after finishing this game, it will slowly enter the ninth season.

RNG and G2 are both the team names of League of Legends. RNG is a Chinese team and G2 is a Spanish team. In this League of Legends S8 global finals, RNG has won many championships in large and small games this year, and has high hopes from its Chinese partners. Even before the game started, many platforms predicted this championship. There will be at least one spot for RNG in the competition, but unexpectedly in this competition, RNG actually lost to the peripheral team G2 in the quarterfinals. The huge disparity in strength between the two has aroused heated discussions among many netizens. If you don't quite understand how subversive this incident is in the minds of fans, just imagine the scene where Sun Yang didn't even make the top ten in the game.

Ciancan Tudou is the author of the famous online novel "Fights Break the Sphere". He also has many other masterpieces. He is one of the leaders of the post-90s Internet era and has the right to speak in the current post-90s Internet environment. It's quite heavy; this time he angrily criticized the RNG coach on Weibo and questioned the winning rate of the peripheral teams they spent a lot of money on (the winning odds of the peripheral teams are extremely high), saying that they were so inflated that they simply didn't deserve to win.

Netizens have been discussing Tiancan Tudou’s remarks. Some netizens thought that Tiancan Tudou’s attitude was a bit too much. Although everyone was disappointed with the result of this competition, his behavior was excessive, saying that he was just taking the opportunity to gain popularity. In response to this, Tiancan Tudou said: The reason why he is so angry is because the beating was too bad. He said that he has always watched RNG games, and the one he supports the most among the three teams is RNG. But this time it was really disappointing. Many netizens agreed with Tiancan Tudou's statement that inflation and underestimation of the enemy were indeed the main reasons for RNG's failure.
