Gambling is for everyone. Some countries can impose age restrictions, but nowadays, online gambling has become more and more popular already, and take note that these online gambling websites don't have KYC therefore, they don't know the age of the users who are gambling. With this, those who are 18 and below can still gamble.
Yes, gambling is for everyone, but not everyone can be successful with gambling. Yes, you can gamble, but your success in winning is low.
So what about those who are inexperienced on gambling? Are they also part of the gambling industry? Because gambling needs experience and luck.
What do you mean when you say inexperienced? Once you gambled, you have experience already. Once you gamble, you're part of the industry already. I mean I don't know what you mean when you say "Inexperienced". Well, did a quick google search and it means "little knowledge or experience". Still, little experience is an experience, therefore, and what I know is that everybody who has experience in gambling is part of the industry already unless they'll quit permanently.
