Short answer, yes, but with discipline and patience anyone can do it.
Long answer -
Back in the early 80s, a couple of very successful traders made a bet among one another. One of them would take a bunch of people off the street with no trading background at all and teach them how to trade. He taught them his system and it's said the 14 traders made around $150M in five years. They're called the Turtle Trading Group.
Anyone can be a trader, but 95% of people who attempt to do it will fail. Some will crumble under the pressure of trading with real money. Some because they don't use proper money management. Some because they don't stick to their system's rules.
The three key factors that make a good trader are: psychology, risk management, and the system / edge.
Psychology because it takes a certain mindset. How are you going to react when your trade is $100 in profit but looks like it's going to turn against you? Even if your system said the target was $200 profit? Are you going to close it out there on emotion or do you let your system's rules guide your decision? There's also no trader in the world that can boast a 100% win rate. How are you going to react to losing your 8th, 9th, or 10th straight loss in a row? Sometimes that's just how the odds play out. Traders and poker players have a very similar mental makeup and approach to their money management.
Which brings us to the next factor, risk or money management. As previously stated in the thread, you should never risk more than 1-2% of your account per trade. Additionally, every trade should have at least a 1:1 return on risk. That is to say, if you're willing to let a trade go $200 against you before closing it then you should at least stand to gain $200 from it. Preferably more. These two rules will allow you to grow your account even with just a 50% win rate.
Lastly, is your trading system or edge. These are the rules you trade on that give you a way to reliably identify opportunities to take profits from the market. There are hundreds of published systems out there. Moving average crosses, volume based entries, breakouts, trend trades, counter trend trades, news based, and numerous others that I can't name for sake of time and space. Look into them and find one that you feel comfortable trading. Or if you're particularly astute you can always create your own.
There are plenty of trading-based websites and forums out there. But as with any other place on the Internet, you have to separate the chaff from the wheat.
