I do consider trading as gambling. What is the definition of gambling at first need to know that. A attempt in gambling either will bring you some profit or loss. Trading where you get data and make analysis and then based on that you do a move to put some money in something. You think this is good thing to get profit sometimes you make or other times loose. Even experienced traders can not avoid losses as it is not in your hands to control the market. They work the same way in my point of view.
Agree, they are might both the same on the risk because you are risking you money on both fields but still trading would have always an advatages since their are things or tools that could able for you to be profitable on trading but as you said we would definitely experience lose trades but as long we are knowledagble enough we could lessen it for sure.
