Your perception is wrong and the advice is not smart, day-trading is part of trading styles that have "blessed but also ruined" people's finances just like any other style of trading you can talk about, holygrail doesn't exist in trading. Still, if you know your day-trading strategy very well, manage/plan your trade rightly and are disciplined, then you will have good results. However, trading is risky, it is either you risk it or leave it.
No, it is not wrong, because with the thread what I wanted to put is a contrast to all those ads and influencers who sell you that learning a little trading you can make money easily. The statistics are there, however much the trading houses that live on fees and influencers who charge for promoting trading do not show them or underestimate them. For someone who has never traded before and is considering starting now, they are likely to lose their capital.
