Gambling is entertainment for most people but for some people gambling is a job. Poker players mostly but also some sports bettors or horse races bettors.
You mean, for the idiots?The categories of bettors people you mentioned aren't in any way comparable to web dice bettors. There is no TV, no sponsors, no bribes on web dice betting. Eg,
I bet poker players get more from sponsors that from winnings.Keep betting and you will lose everything. The fact that you are not able to make money from poker and that you are so narrow-minded doesn't mean other people can't make money playing poker.
I pay taxes on my poker profits every year since regulation was implemented into my country, and before I had profits every year but I didn't pay taxes. Few people, poker pros, have poker as a job but there are many others, known as regulars, that have it as a side job and gives them extra income. They have no sponsors and they don't appear on TV.
See how many people here appear on TV or get money from sponsors:
