different things for different people i guess
You cant understand why most people love football and get excited and have the we thing and i would say the large majority of the population say the same about e-sports. It might be big for you but if you stop 100 random people in a street (one that isn't in a uni or something) then you might get 1 who even knows what LoL or Dota is (if you grab a few youngsters i guess it might be higher)
That will prolly change for sure but i have my doubts that it will ever be big in England at least.
Call of Duty well now thats a different story most people know what that is at least
CoD and BF is pretty mainstream and appeals to the casuals and even most of my mates who love football etc play CoD
(and fifa)
