So I think an experienced trader is much more valuable than a gambler.
There is no doubt about that. Gambling, in general, is a way to try your luck, but some people take it differently, and they are wrong. If you think that you can make money from gambling on a constant basis, then you are wrong, and this wrong mindset is going to cost you money whether in the short or long run. If we do a survey asking people who took gambling as a source of income how it went, barely 5% of them would say it worked for them because it's not meant for that purpose.
Trading, on the other hand, can be a career choice because if you gain enough knowledge, increase your experience, have a good budget, and learn to stay patient in certain situations, you can make good money from trading in the long run. It's all about making the right decisions at the right time.
