No such thing as a
watched the video because I am obviously sure that no such strategy exists which guarantees a profit, but I visited the link given in the description and it took me to some wild casino (literally, that was the name of the site after many redirects) and it was a referral link from what I understood. If someone is sharing referral links, it's pretty obvious the guy is trying to earn by affiliate revenue and doesn't have a working strategy. If you have a working strategy why would you need referrals then.
Also if ever there was some trick that somehow existed to make money from casinos, it would be exploited rather than being shared.
Probably a clickbait title. The casino (or a person who joined their affiliate program) is making videos like those to attract people to the casino. But you should still be careful when clicking on random links. And yeah, there are no "such" thing as profitable strategies. Even if one did exist, no one would be sharing those strategies as casinos will find a way to stop people from profiting from that specific strategy or they will all go bankrupt eventually.
