i think it means only one side is open, but i just need to make sure

Perhaps you should give the phrase to us in context so we can assess.

You will see nodes forming at the closed side of the pipe.
It prevents the air from vibrating at that end.
The waves are reflected with an inversion and thus
interferes destructively forming the node.
At an open end the waves are reflected without inversion
causing constructive interference and forming a large
amplitude vibration at this end of the pipe.

You have to blow the pipe, so one end must be open :)

We don't know if anything is being blown into the pipe. Sound could be transmitted through a diaphragm at one end.
As DaveC426913 writes, we need the whole context.
