My question is do you think gambling every day is better? From his reasoning and points of narrations.
Your friend might be onto something if he's tried this method successfully without becoming addicted. However, gambling daily isn't advisable for a responsible gambler, as it can develop into a bad habit and lead to addiction. There's no guarantee of increased winning chances by playing every day, but you might gain more insights into how the games work. Yet, the risk is becoming addicted and relying too much on gambling for income. To avoid the pitfalls of addiction and financial losses, responsible gamblers should steer clear of such frequent gambling. It will make more sense to focus on the potential negative outcomes rather than emphasizing the positives side of this method.
You're right when you say practicing a game might give a player more insight about how it works. But it won't necessarily give the player any greater advantage over the house because anything can still happen. It's really not how much a person knows about a game, but more of their ability to control their behavior and avoid the Falling into the traps of addiction.
