Trading can make you rich if you are already rich.
Though I don't know your definition of richness, but for you to make a huge fortune to turn a rich man you will have three things;
1. Trading skill: Your skill should be a way above gambling, you should have working strategies and have a good knowledge of the charts.
2. You must have good start up capital. You cannot start trading with $100 and expect to become an overnight rich man.
3. You should have a good risk management and then don't be greedy or in other words, be patient.

Goodluck!
