I clicked up the link and just check it out.Those advises are just common points and i fully disagree on one of those which is Gambling.

I agree with you. Gambling is not a good way to make money but it's a lot risky. You might actually end up losing your funds if it's not your luck. There's no assurance that you'll get good earnings through it. There are actually better ways to earn but you have to exert an effort and spend time. Bounty hunting and airdrops are also ways to earn but you have to look for legit and paying projects.
