gambling is like business where people look to make more money from investing little money but most of them will get failed.
Gambling is nothing close to investment man, Your quote is fully wrong. In "investment" you're using analysis to calculate will this investment be successful or not, and the influence of probability is significantly low. And vice versa with gambling, where house of edge and EV is always negative. The only way to invest in gambling is to open your own casino
that clearly then its totally different because gambling is really intended for entertainment purposes and has nothing to do with investment yet
its a different thing to talk about.
