Nah advertising to kids is a bunch of bullshit. It should not be allowed in general and definitely not for things that are harmful to them.
I can't think of a situation where that's true.

Home delivery apps do that. Although I am not sure if "pound "is a unit for weight or currency in this case.
If it's currency - in the UK, there are mandatory loss limits (esp. for new accounts). If weight thousand[s] of pounds is unrealistic gain to anyone.
Obese people, on the other hand, continue to eat despite knowing it makes them fat and unhealthy. It's an addiction just like cigarettes and should be treated the same.
Different people have different preferences. It's like saying anything that provides only recreational/etc. value has not utility.
People also build community around it and make friends.
Certainly sports betting makes watching professional sports (which have no utility) far more interesting. Like spiking a drink.
It pays for newspapers.
