It is true that Esports are getting more popular these times of the pandemic but I doubt that it will ever be more popular than sports betting.

It is true that the viewership of each tournament is increasing but that we can't always relate that to betting since we can't always say that if there are a lot of people watching, there will be a lot of bets on it since not all of them are betting themselves. Sports bettors are not even watching the game itself, they watch the replay or just look at the result of their bet directly to the site.
