Every meridian of longitude has nominally the same length, because
they all connect the same two points ... the north and south poles.
The map you are referring to is likely the Mollweide projection. It is an equal-area projection that represents latitudes as straight parallel lines and longitudes as elliptical arcs. This projection aims to minimize distortion in terms of area, but distorts shapes and distances.
The horizontal lines are called latitudes and the vertical lines are called longitudes.
All longitudes are measured as arcs of great circles that extend from the North Pole to the South Pole, making them equal in length. Unlike lines of latitude, which vary in distance between them as they approach the poles, longitudes maintain a consistent length of about 69 miles (111 kilometers) apart at the equator, converging at the poles. This uniformity is due to the Earth’s spherical shape, where each longitude represents a division of the globe into equal segments.
Longitudes are lines that run north to south on a globe. At the poles, longitudes converge and meet because all lines of longitude, or meridians, come together at a single point. This means that at the poles, there is no east or west direction left to differentiate between, so the longitudes effectively merge together.
Lines of latitude run parallel to the equator. Lines of longitude run vertically - passing through both poles.
Latitude lines are parallel but not longitude lines.

-- they are semi-circles -- they are not parallel -- they join the north and south poles -- they are perpendicular to the equator -- the higher the latitude, the closer together any two longitudes are -- at the poles, all longitudes are the same point -- for every longitude west, there is an equal longitude east

They are lines of longitude and latitude, often just longitudes and latitudes.
Longitudinal or longitude lines are the imaginary lines that are perpendicular to the equator. Latitudinal or latitude lines are parallel to the equator.
