Some people choose to use streamers when they are ready to find their first casino to gamble, but I call this a very bad idea because most streamers are not using the same software that will be available for gamblers when they sign up on the same casino as the streamer.
Many people have walked the same way with streamers, using their same method and also same platform and yet they don't get the same result, in fact the result is nowhere near what the streamer got, I am not saying that all of them are the same but most of them are.
Why not focus on yourself instead? There is no amount of gambling strategy that can make you win money without losing, the only choice left is risking what you can afford to lose, nothing beats this idea in gambling.
Notwithstanding that the streamers use some form of software different from that of their users, as you said, strategies don't work the same way for everyone, still. However, I don't know if gambling streamers use different software, because the casino only makes use of gaming providers. It'll be rare for the casino to have a provider customized for the streamers. There've been lots of rumors about the winning outcomes of streamers, but the casino indeed gives some immunity to the streamers to win more than other people for promotional purposes. How they do it, we may not say that we are sure of the tricks or techniques. What I could figure from it is that the users play with their money, while the streamers use that of the casino to gamble. Which offers them more confidence than the other gamblers. Because other gamblers are conscious of their funds, while the streamer gambles whatever prediction that comes to mind. One party, the streamers is not worried, which boosts the results of any gambler. Don't also forget that the streamers lose huge amounts of money, in the process.
The only difference remains that they get big wins because of the high amount they wager. So, newbies who follow their gambling techniques are not doing the right thing and should blame streamers for their mistakes. Gambling is a person's choice, doing some other person's thing isn't rewarded like the owner. In a nutshell, your last lines conclude it, the player should manage their money and not fall victim to chasing losses. Wherever, they gamble it's important to manage their money, not to regret or have anxiety in the process. If the streamer wagers a huge amount of money, a newbie shouldn't try the same technique. He may not afford to lose such an amount of money. Those are just for promotional purposes and gamblers shouldn't take them seriously. They're more like demos and it's not something to influence the decision of gamblers to act like the streamer.
