Good point. People (like me as well) are easily confused by he term "strategy" as i never really thought that even unproductive strategy, that is doomed to fail and based on gambler's fallacy is still considered as a strategy. But i recon that in sports there are more ways to implement different strategies, as you can do ton of research about the players and teams. I am not saying that they work, but they might have better changes working then using it with house edge games. And i would say they can give way higher edge then just playing with low odds.
And obviously those strategies can work in poker. Only proof i need for that is the fact there's often same groups of people ending up in last tables in poker tournaments.
As for me I already know how this strategies works and since also I am aware that there is not working strategy anywhere that can guarantee a steady winning or any winning at all unless based on luck this make me to have clear and better understanding of what the ops mean when he mentioned strategy, and what wasted efforts it is if you depends on such a strategy to win any bet at all, most of the people that make such statement are all doing so because of they own benefits since if you ask to see such strategy they may ask you for a few and when you pay, you likely to lose but the money you pay for the strategy and even your betting money as well, so is of no use having such a strategy or using such strategy to bet since ithe strategy doesn't work.
