The reason is because current is a measurement of flow - how many electrons are passing through the wire, whereas voltage is a measure of the difference is energies between two points.
In order to measure the amount of electrons passing through a wire, you actually have to place the multimeter within the flow. To measure flow, the multimeter places a VERY LOW resistance into the circuit and measures the voltage drop across that resistance. By using a very low resistance, the multimeter has a negligible impact on the circuit when placed in series.
In order to measure the energies between two points, the multimeter is place in parallel in the circuit with a HUGE resistance and measures the current through the resistance. By using a huge resistance, the multimeter has a negligible impact on the circuit when placed in parallel.
Note: when placing a multimeter into a circuit in series with it turned to the voltage setting or in parallel with the current setting, you will either destroy the multimeter or trigger the circuit breaker or fuse
