The fact is everything that has to do with gambling depends on luck to some extent because if you base your bet on analysis alone, you sometime make wrong analysis but again I believe in skills and experience because you can't depend on luck without any prior information or experience. Slot is a luck-based game, just a game of numbers but if you bring an experienced slot player and a novice to play slot you will see that the player with experience will do far better than a player that depends on luck without any experience.
The only advantage of experienced slot player to newbie slot player is the level of patience but no other than that if we assume that both newbie and experienced slot player has same bank roll, amount of bet and total number of spin because slot is purely luck based as you said already and there’s no define strategy on playing rather than adjusting your bet size since the result of each spin is totally random.
But in other sector of gambling such as card games & sports betting highly dependent on skills than luck so analysis is very important after all.
I agree, slot games are totally just basing on RNG, volatility, RTP, luck, and chance. It doesn't require game analytics just like other games such as poker and Pai Gow.
I had played a lot of slots, I spun lots of reels. Maybe I can tell based from my experience and pre-knowledge that slots are game of chance.
In my opinion, if you want more chance to win on gambling, maybe try building up your skills on skill-based gambling games. Just an opinion.
