If you take the lottery as a lucky event, it might be something like poker. But in truth, there are players who play poker like the lottery and they really don't do too well.
A sport is not. A mental sport can be. If you need to have a fresh mind to make decisions continuously, about skill, about strategy, about positions, about the game of your opponents, about mathematical possibilities and others. Very quick decisions are made on many issues at once in every moment you play.
You must always have discipline in all walks of life, and poker is no stranger to discipline. And this must be in every sense, at the education level, at the earnings level, at the level of bad streaks and others. If you don't have discipline it's impossible to play and I estimate that at a higher professional level the discipline should be even greater.
In short, I think it's not like the lottery but you must be lucky. It can be considered a mental sport and if discipline is necessary, this option has no objection.
