Can learn? -- I'm sure! Will they learn without any "encouragement"? -- Absolutely not. There are millions of people struggling to get on a diet, to quit smoking, to stop doom-scrolling their choice of social media. Most of them know very well how good it would be to stop doing bad things and start doing something good instead, and yet they don't. Children are worse, overall, because life isn't as harsh for them as it is for adults. An alcoholic who can't quit drinking is risking his marriage, his career, on top of his health, and still pulls out a stashed flask and takes a sip. The worst that can happen to a child is that their parents will yell at him / her? That's a very weak deterrent against doing something that offers instant gratification.
