E-sport is just a niche at the moment, so you will only find games like CS: GO, DOTA 2, and LOL simply because these games have many events, and its user base is enormous compared to other games. That being said, the number of users is the most crucial thing if you want to host some event.
Anyway, back to the topic, if you host amateurs, I don't think you will attract enough number of bettors to be profitable. Perhaps 1,000 amateur events only equal to one professional event if we talk about the number of bettors and profit. So why bother?

Yup, no one would take the risk to host one for amateur players unless the host is really looking for a future pro player. Just like how a basketball coach would watch a tryout games for amateurs to find an aspiring player. But if you want to see an amateur tournament online, I think it is not profitable. I saw tournaments like this whenever there's an event connected to the sports and it is done in a certain place. For example, launching of a new gaming software or a gaming phone, or anniversary of a brand used for gaming, etc.
people would be more interested on seeing or betting into those teams which had already established out their names for longer years rather than betting blindly on new ones.
E-sports is indeed becoming bigger and bigger as years passed and we have seen several games do even hit multi-millions on prizepool when it comes to tourneys and
also its been some quite time that bookies already making out lines for these events.
). You also need to consider advertising but that comes easy when you have outsourced the players.
