A single slow sink or tub is usually a localized clog, hair and soap in a bathroom line or grease in a kitchen line, and a cable machine typically clears it. When every drain in the house backs up at once, or a floor drain rises when you flush, the blockage sits farther down in the main line, more often root intrusion at a clay pipe joint, a bellied section that no longer drains downhill, or a blocked vent stack that shows up as gurgling.
Stop running water into any drain that's backing up, and skip the chemical drain cleaners, which can damage older pipe. A main line clog, sewage odor, or gurgling from several fixtures at once are signs a cable alone may not be enough and hydro jetting or a camera inspection is worth asking about.
