Yes, a lot of people think that. The “official” dollar value don’t exists 😕 If you want to buy that dollar, just a few people can buy it in the banks (and just $200) because there is restrictions, but even that, you have to add taxes to that official value, so the current official dollar value is 433 pesos (251 pesos + taxes), so people buy “illegal” dollar (also called dollar blue) in an exchange, that dollar cost 493 pesos, that’s why the picture you posted is wrong .
