false ribs
No, not all ribs directly articulate with the sternum. Ribs 1 to 7 directly articulate with the sternum, while ribs 8 to 10 indirectly articulate with the sternum through the costal cartilages of the ribs above them. Ribs 11 and 12 are floating ribs that do not articulate with the sternum at all.
There are 12 pairs of ribs that articulate with the thoracic vertebrae, one per vertebra. The upper 7 pairs of ribs articulate directly with the sternum, either via their own costal cartilage or the cartilage of the rib above. Ribs 8-10 articulate indirectly with the sternum through a shared cartilage, while ribs 11 and 12 are floating ribs that do not connect to the sternum.
According to Ross and Wilson Anatomy and Physiology, 2 pairs
True ribs (ribs 1-7) articulate with the vertebral column at the thoracic vertebrae and also attach directly to the sternum at the front of the chest through costal cartilage. This connection provides structural support and protection for the internal organs located in the chest cavity.
Because they do not articulate directly onto the vertebrae.

True ribs
In humans, there are 12 pairs of ribs. The first seven pairs, known as "true ribs," articulate directly with the sternum via costal cartilages. The 8th to 10th pairs, called "false ribs," articulate indirectly through the costal cartilage of the rib above. The 11th and 12th pairs, known as "floating ribs," do not articulate with the sternum at all.
costal cartilage.
The clavicles and ribs are lateral to the sternum. Both bones articulate with the breastbone.

the bottom 2 do not connect to anything, the rest join at the sternum or breastbone
In the posterior position the ribs articulate on individual vertebrae of the spine. I the anterior position they converge on the sternum. There is no bone in the centre of cage made by the ribs.
Because they do not articulate directly onto the vertebrae.
Ribs are classified according to their attachment to the sternum. The first seven pairs of ribs attach directly to the sternum and are called true ribs. Ribs 8-10 have cartilage that attaches to the cartilage of the seventh rib and are called false ribs. The eleventh and twelfth ribs do not attach to the sternum and are called floating ribs.
