i think if you someone expert in gambling then anyone do not need to easiest way to earn profit if you are expert and skillful in gambling and i think these thing is very important in gambling.
Not even experts in gambling can make easy profits in gambling,and there is not much skills required in gambling,you require self control,experience and a lot of luck which is not always possible,so no one can make easy profit in gambling,but yet this can be minimizes if you have self control.
Yes, maybe they have a bit advantage but even they have a bit advantage because of their skill that doesnt mean that they are going to win. For example in poker, you are skillful but how about if your opponent is skillful like yours it means it still not an easy way, hard instead.
