Anyone dumb enough to fall for these is pretty much their target audience.
That’s actually exactly the truth. They intentionally make these somewhat obvious to weed out people that will figure it out quickly. They want the extra greedy, the easily confused, the elderly, the intellectually disabled.
Exactly. They rely on 'the law of large numbers'.
TL;DR: You send out 100 emails/marketing/notices/etc., you get 10 responses, you get 3 inquires, and land one 'fish'.
In
probability theory, the
law of large numbers (
LLN) is a
mathematical theorem that states that the
average of the results obtained from a large number of independent and identical random samples converges to the true value, if it exists.
[1] More formally, the LLN states that given a sample of independent and identically distributed values, the
sample mean converges to the true
mean.
The LLN is important because it guarantees stable long-term results for the averages of some
random events.
[1][2] For example, while a
casino may lose
money in a single spin of the
roulette wheel, its earnings will tend towards a predictable percentage over a large number of spins. Any winning streak by a player will eventually be overcome by the parameters of the game. Importantly, the law applies (as the name indicates) only when a
large number of observations are considered. There is no principle that a small number of observations will coincide with the expected value or that a streak of one value will immediately be "balanced" by the others (see the
gambler's fallacy).
The LLN only applies to the
average of the results obtained from repeated trials and claims that this average converges to the expected value; it does not claim that the
sum of
n results gets close to the expected value times
n as
n increases.
Throughout its history, many mathematicians have refined this law. Today, the LLN is used in many fields including statistics, probability theory, economics, and insurance.

This is also how MLM works.
