No. Arteries, which carry blood away from the heart are usually thick walled and round shaped.
Veins on the other hand carry blood to the heart and are slightly more thin walled and more elliptical in shape.
Capillaries are the smallest of blood vessels and very thin walled. They carry small amounts of blood relative to veins and arteries.
Relative to the walls of arteries, the veins' walls are thinner, because the pressure of the blood in the veins is much lower; so low in fact, that valves are required to prevent blood in the veins flowing backwards.

there are only 2 vessels that take blood from the heart. The Pulmonary trunk that bifurcates into the (right and left) pulmonary arteries. and the aorta. the aorta is the largest vessel in the body and certainly would be considered thick walled.
The thin walled blood vessels are called capillaries.
Arteries are thick-walled blood vessels that carry blood away from the heart. They usually carry oxygen-rich blood, except for the pulmonary artery.
The veins are neither strong nor thick of the blood vessels. On the contrary the veins are thin and thin walled. The arteries are strong and thick. They have to bear the pressure of the blood that comes from the heart.
Arteries ALWAYS bring blood away from the heart. Vein bring it back.
