Anyone who is gambling minded is as same a trader, because a trader is curious to watch over it's trade and it's desperate about watching of the trade against lost.
A trader, if a real trader, is far from being a gambler. True, they can both lost but the advantage of a trader is, they use skills, knowledge, experience and data to do their jobs. They do not use pure luck to become successful in their field. There is luck but a greater part of their success is because of the knowledge and research they have done. Every move they make is all a calculated risk.
Gamblers, on the other hand, especially casinos, rely mostly on luck. There are very few games that you can use skills to win in gambling. An example is sports betting and poker. In other games, you need to have extreme luck in order to sustain winning.
