of course, putting money in lottery is gambling too. why did you make this kind of question?
do you do not really understand the meaning of gambling?
i think he just want to receive the views of the people as you can see that different people have given different types of answers, and in my point of view i will like o say that lottery is a type f gambling in which one has to depend totally on luck and there is no concern of skill or experience in lottery gambling.
Probably this is only for the discussion purposes and I do not believe that OP is that innocent who does not know the meaning of gambling, he may think that since the money involve in lottery is relatively low, he thinks it's not gambling but just for fun.
