Good advice. I can say that (although this is paradoxical) one of the best luck for a beginner is a loss. Losing and unpleasant emotions associated with this give an understanding that there is no easy money here. If a novice player wins, then he might think that this is normal. And then when at a distance he will suffer losses he will not stop but will continue to play expecting his luck.
It also have have different approach if the newbie when the game since the outcome will different for that matters, I've seen so many newbies got addicted when they win their first bet so this discussion really depends on what type of person the gambler is. If they have self control then theirs no problem even if they are skill based or chance based games.
