Even when analyzing teams in sports betting, your winnings depend on your luck! In trading as well, sometimes the market does not move according to your predictions... Of course, more often the one who has knowledge wins, but a lot depends on luck!
Yes, we still need our lucky, which can support us to win the games. So we can see that both trading and gambling will need the luck to make money, but the chance to lose will be bigger in gambling than in trading.
I agree.
Trading with big amount or what you can't afford to lose without the required knowledge/experience is basically gambling. Same as other bettings, like betting in skill-based games, sport betting, poker, politics, etc.
I believe a good poker player for example could win consistently with his/her skills. The good and successful ones are probably few
But even if that player has a high-skills in poker games, he cannot play randomly without thinking about making a strategy to win and depend on his luck to win. But remember, that even a good poker player will not always have their luck comes in the poker game because we don't know when the luck will come.
