Yes physical gold is money (also physical silver) whereas all those fiat currencies you mention (and all fiat currencies used in the world) are just that: 'fake money", currencies (not money).
The rising "price" of gold in a fiat currency, like in your chart, just shows the value of that fiat losing value, or purchasing power, over time rather than the gold increasing in "value". Never save in a currency, but in real money.
A simple analogy is a plane full of skydivers: the skydivers represent currencies that bob up and down relative to one another after they jump out of the plane. Gold on the other hand is the plane that follows a level course. Eventually all the skydivers reach the ground, like currencies with a value of zero.
