Just be sure to note that the left side pedal (as you sit on it) has a left-hand thread: https://www.parktool.com/en-us/blog/repair-help/pedal-instal...

Yep!
The threads are different in their direction per side so that the rotation during forward pedaling further tightens the pedal.
Another related interesting fact is that on a unicycle, especially one used by someone who can ride backwards, needs to be checked often to ensure the pedals don't back themselves out due to pedal rotation in the opposite (loosening) direction.
