Yes, that's right, not only does it trigger an increase in adrenaline but it also triggers an increase in hope and belief that they will be able to achieve a big win as they see from what the streamers produce in the show which indirectly they hope that the amount of big wins will be able to change their lives for the better financially.
On the other hand, I also agree that what is done and shown by the streamers really does influence the perspective and way of thinking of gamblers in viewing gambling, many of them eventually get lost in a wrong understanding and of course as we know about how dangerous it is and what bad potential will befall a gambler when they already have the wrong perspective on gambling, of course over time without realizing it they will be trapped in a cycle of addiction where when they win they will be greedy and when they lose they will be even more curious.
The reason why many followers loses their money as they are hoping that they can also have that same success that streamers are sharing, they are being blind by the reality that its all for the sole purpose of advertisement and just to make sure that they'll be able to reached those followers who also have that same passion with gambling, streamers are sharing those kinds of activities to earn money directly from the casinos or indirectly by form of ads and referrals.
On the other hand, I think being rational and maintaining common sense can help someone avoid something that is misleading, because by being rational, I think you will know what looks reasonable and what looks far from realistic, so for this problem it depends on how each person responds to everything they find.
