The line or crossbar across the 7 is to distinguish it from the numeral 1 when it has a serif on top, making it look like a 7.

The line across the Z is to distinguish it from the number 2, which may be mistaken as a Z when hand-written, which is especially important in mathematics.

Why does the European number 7 have a line through it?

Many Europeans write a 1 with a rather long "flag" at the top but no cross mark at the bottom, so that a 1 and a 7 can sometimes be mistaken for one another. The line through the 7 distinguishes it in the way that the line through a Z can distinguish it from a 2.
