I want to run motors and servos from the I/O pins. The videos said that it requires more current than the output.What should I Do?

What should I Do?

Servos do not need more current from the output pin than the Arduino can supply.

Motors on the other hand do.
You can use a transistor or a relay to control the motor. See:-
