The OP didn't say fantasy sports betting is not gambling. It still is but there's a difference in level if I understand what libert is trying to say correctly. It's not as simple as the game happening virtually but you get to pick or assemble a team to compete. We can look up on the other mechanics but the bottom line is that it's as if you're the manager so you have more control on the outcome of the match and that's not possible in pure sportsbetting.
