It completely depends upon the person how he treats because myself, I will consider gambling for fun, today we are living in a stressful life and everybody are looking out for some fun and entertainment. People who are looking for fun will not invest much amount into gambling.
It happens that simply fun can easily become an addiction! And you won't notice how you start spending more money than you can afford!
So you don't need to be too fond of gambling! And need clearly understand it's entertainment for you, or the beginning of addiction!
