No, if I see and advert advertising something then it’s an ad. If OP had gone to the guys merch store the listing would not be ads, but they are being advertised below the video.
It’s about intent, a sign at the food stall isn’t an ad because you are already there intending to buy something, but if they advertised the popcorn in the theatre itself then its an ad since you aren’t at the theatre with intent to buy food.
So when OP clicked the video he wanst intending to buy from the merch store so it’s an advert because its trying to convince him to go to the merch store and spend money.
