Sometimes some people just spin the same game in every session they do, it doesn't matter and it's pretty good if the game gives you a win quite often, but if you play but it's very difficult to get a win or even never give a win by the game you play then obviously they can follow the advice you conveyed this friend, several games or even thousands of other games can be for them to try, It is possible that their luck is in some other game that they have never touched before, and if you do not understand how to play then obviously you provide very good by trying first on a demo account, it is better than you immediately try it with real money but absolutely do not know how to play and maybe it will only cause many mistakes to occur which will also clearly waste more of their money.
For the initial stage, honestly, I would advise them to try the demo mode as you said, because even though they don't mind losing, what they are betting is money, so the initial statement above as you said would be more effective to try and learn.
You can practice in a secure, shark-free pool (demo mode), so why throw caution to the wind and go all in with real money? God bless us, as humans, we tend to overestimate our own skills. Although we believe we'll be the next big winner, most games are actually made to be difficult. Isn't it what makes the hunt so exciting? It is what entices us to return for more
Remember, nevertheless, that gambling is a game of chance rather than ability. Changing games to try and find luck is similar to sampling several varieties of ice cream; you might discover your favorite or you might just freeze up. In the demo mode, you can practice without having to risk any of your hard-earned money. It's sensible, useful, and, let's face it, a lot less painful than discovering pricey mistakes
Yes just to practice and understand how the demo account game works is a pretty good and effective choice, well that's right sometimes we like to overestimate our own abilities in any case when in fact we have a limit but they don't seem to pay much attention and care about that even though on the other hand understanding related games and how to play is quite useful too at least to reduce things that are not wanted especially defeat because of ignorance of how to play. Of course, most of the games are made difficult, which is what makes the bookie richer, because otherwise they might go bankrupt. Beginners don't realize the difficulty of winning, one win makes them curious and want to make 10 tries, on average more losses.
That is why gamblers, especially beginners and even professionals, must still apply caution and a high level of vigilance, none other than because gambling is entirely just a game of chance if you want to earn, and also another thing is that gambling is established for fun and that is why people who are looking for income get the opposite result, meaning that instead of winning but losing a lot. The purpose of a demo account is probably one of learning, casinos still care about you so they created this alternative.
