That's right. In fact, esports is just easy to predict when you really know the game and who the players are. Mostly those team with a player with high ranking in the game are considered a strong team so placing our money to them is a good idea.
I disagree with your point of esports being "easy bets". No gambling game in the world is easy. Even if you are really good at the game, gambling on a outcome of a game is also based on a lot of other factors. You need to know the team members and if the matches are fixed all your predictions could go wrong. eSports is more like a fixed version of any other physical game, its just promoted and gamebois are just too excited to join in it forgetting that the age old laws of gambling still apply to it but really who cares about the money?
Analysis of the game will help you but the outcome of the game can be due to a lot of luck factor.
