"I had a feeling it was bogus."
I've always ignored those sorts of things entirely, on the theory that I don't believe the entities in question are capable or willing to put the engineering effort to provide a number accurate to two significant digits at scale.
Also the numbers are often implausibly large. If there's "one" of an item left and "43 people" are "currently looking" at it, then the problem isn't that I need to hurry up and buy it, the problem is that you've utterly failed at one of your basic tasks, stocking correctly for demand. In general, businesses are actually really good at that; it's literally life and death for them, so the idea that every single thing on their site is just on the verge of selling out unless you get it now is just absurd.
I've been trying to train myself to ignore "discounts" too, unless I can prove to myself that there really is a difference between the "real" price and the "discounted" price and there is some specific reason that I'm getting the latter. Or to put it another way, "customers in general" don't get discounts. You can get a discount if you are "a price discriminating customer willing to hunt for coupon codes", or "a friend of the proprietor", or something specific, but you are never just handed a discount. Those discounts are discounts... they're just the price.
