Stock market is the game of gambling or not?

A most heard line is that the Stock Market is Gamble. If we discuss regarding stock market then everyone will tell that it is purely gambling. Instead of this people will also give their free suggestion that is Stay Away from it. Are they wrong? If we talk about this then they are not wrong then another question arises that if they are not wrong it means the Stock market is gambling. So Let's discuss this point.

Actually now I want to clear your concept that people have watched other people lose their whole property and money in it but the reality is that they lost due to lack of knowledge. If you don't have knowledge related to any field and still you started a business in that field then it is clearly gambling.
Let's take an example to make it more clear suppose I invested 10 lakh rupees in any business but I don't know anything regarding its market/ competitor/ etc. then what will happen?

Is any possibility that it will run well?  Obviously, the answer is No. Now this will come under gambling because without Knowledge Everything is gambling and
Earning comes only after Learning.

Here I am not suggesting you to enter in the field of Stock Market. Our motive is to aware you that you have to focus on learning then surely money will find you.
