Of course they are trying to take your money, but so does every business in the world. Apple doesn't just stop at making phones and not taking any more of your money. And every company that we trade on the stock market does the same. It's their job to generate money from various income streams.
Anyway, I've just watched several more of Steven Dux videos and really like this guy. He has a very good, solid approach to shorting penny stocks, with lots of good points and advice. Everything checks out, maybe except his profits look a bit extreme, but still possible. My backtests show 500%+/year profits on such shorting strategies with moderate risk (not low risk). It would be starting with max $100K due to limited capacity, and require trading somewhat large size like 10%/trade. But an actual day trader can analyze more variables, news, level 2, make decision in seconds, scale-in, scale-out, adjust stops, etc. - that's a lot of things that can give him advantage.
He seems to be able to take higher risk by setting up a $25K account and then making as much money as he can with a risk of a blow up, but then he can setup a new $25K account and start over. This isn't a bad approach and also used by some Forex traders. Though he may be using this for marketing so he can blow up several accounts until one of them makes $1M.
The conflicting broker statements from Dux do worry me, so I am skeptical, but it's not like absolutely no one ever made a $million dollars trading penny stocks. And if any one person did, then a few other might to, especially when well prepared. There is also a pro trader at SMB Capital that makes $2M per year, if I understood correctly from their videos. They offer a lot of free videos and resources, and validate the concept of trading. No one needs to believe or disbelieve any specific trader, just take whatever info may be available from each source. Definitely do not pay for any of that stuff.
