Employed X-ray tech here, this is mostly accurate, but most relevant academic bodies, in the US at least, actually recommend not shielding patients anymore, since it usually leads to slightly higher doses depending on the particular exam.
Collimation of the beam is sufficient to reduce dose with modern equipment.
That being said, when the patient is being X-rayed, such as in surgery, the primary source of radiation for everyone else is the patient. Since that cannot be collimated, lead aprons should be worn, and should be facing the source of radiation (i.e., don’t turn your back when the beam is on, or wear a full wrap lead apron). Even that being said, the amount of radiation is low for almost everything except CT scans and IR (heart cath/embolization etc) cases.
