My hunch is that this wont get passed. These moral signaling old farts can attempt it as many times as they want. Gambling is a huge revenue for the goverment because it can and is taxed by law - how much, depends on each country and its laws, but in my country anything you win through gambling, lottery, random events etc, is getting taxed if you want to claim the prize.
I assume same goes for .... well... everywhere. And if we are talking about loot boxes, big 3A gaming companies who create bunch of money through their services wont just idly standby. Microtransactions for Loot Boxes and similar stuff are huge part of their profit for literally zero effort. And in the end its always about money. Once the shareholders of these companies (who usually have invested money in other companies as well since most of the big companies around the world areowned by a small % of people) see this, they gonna have a discussion with the people in politics and this nonsense will dissappear.
We have seen this before, it just repeats itself.
