The game has the same amount of players that it did before the up-craze in 2015-16, and even before the game came out the cs scene as an esport was always pretty big. It won't die, it's the only game that hasn't lost half of its players after fortnite came out, even if it's playerbase does go down, it will always have the same originals that have always played, the only people that will leave are the people that only came after COD fell off.
