yes of course luck comes first compared to low or high volatility, I also believe that even though the volatility is high in the casino, but if we are unlucky, it is difficult to get a win and vice versa, as you think. 
For a game such as slots, dice, roulette and much more, of course it is true that wins and profits can be obtained due to the luck factor, but don't forget to pay attention to the strategy in playing.But it's different if we gamble with sports betting because sports are matches that we can predict by using our intelligence in doing research.
From the progress of the match, we can also observe it and then we can easily guess who the winner is if we are good at observing and studying the match.
Will you share your favorite "low volatility/high RTP" slots? I would like to see that.
