I often wonder what is a trader? Is it something you can learn then how do you learn it? How can you become good at something if it is like gambling? I see these stock exchange apps on google play and they all show people winning money not losing. It looks just like gambling and you choose up or down. How can you possibly train or study for this? Yet you do get full-time traders?
What you see in those ads are binary options, and they are not considered to be trading. Your observation that they are similar to gambling is spot-on! Many regulators consider binary options to be gambling:
