I'm pretty sure you're talking more about what in forex is called correlation. There's lots of stuff on the forum, on the web and on Youtube re forex correlation.
Yes, some currencies are highly correlated with others, for example the EUR and the CHF, the AUD and the NZD. It follows that some pairs are also highly correlated - EUR/USD and USD/CHF are strongly negatively correlated, so that as one goes up, the other goes down.
These relationships are useful for confirming or questioning a trade decision you have already arrived at.
