I'm trying not to let that electric guitar annoy me... but the fret size is correct but the fret inlays are entirely wrong; double inlays are used to mark every octave (for 12TET tuning) and single inlays mark accidentals(sharps and flats)
Btw this is the very short version, I've spared you guys an in depth wall of text on fret inlays, tuning systems, and how to count frets at a glance
