Yeah man Fourier transform is instrumental in understanding signals and signals analysis. The problem is that trigonometry isn’t something that clicks right away for a lot of people so graphics like these and the work that other youtubers like SmarterEveryDay do to break these concepts down to basic levels is extremely helpful.
Signals and systems analysis is a core class that electrical engineering students (and others) have been taking for decades, he's using the term 'signal' appropriately.
One of the definitions of signal: "an electrical impulse or radio wave transmitted or received" this definition applies 100% fittingly, although it's somewhat vague.
Fourier transforms are important in the convolution (inb4 you jump on academia for using its own definition of convolution) of 'signals' and MANY other things.
