The answer is in the question.
Basically an orbit will orbit the planet/moon while the lander lands on the surface.
The Viking 1 and Viking 2 missions consisted of both an orbiter and a lander. The landers successfully touched down on the surface of Mars, while the orbiters remained in Mars' orbit to relay communications and data between the landers and Earth.

A lander can physically touch down on the surface of a celestial body, allowing for direct analysis of the terrain and collection of samples. This provides more detailed information compared to observations made from orbit. Additionally, landers can deploy instruments and experiments directly onto the surface for prolonged studies.
the difference between a probe and a lander is a lander is a spacecraft that desends and comes to rest on the surface of a planet/space object. while a probe is a device used to collect items and run tests to collect data.
The two missions to Mars that ended in failure are the Mars Climate Orbiter in 1999, which crashed due to a navigation error, and the Mars Polar Lander in 1999, which likely crashed during its descent.
Collecting and analyzing samples of soil and rock are fiendishly difficult operations for an orbiter, but are child's play for a lander.
The lander was used to land on planets and study the such as the moon and the orbiter was used to orbit the planet while studying it.

The ones without success didn't reach mars, or they crashed onto mars.

The Russian orbiter/lander Mars 2 started orbiting Mars on November 27th 1971 == ==
the same thing an astranaut uses. Me? I use my T.I.E. fighter, but most astronauts use a moon orbiter - a small capsule attach to a huge rocket that gets them into space and near the moon. The orbiter has small jets to control where it goes in orbit. In some of the missions there has been a lander that separated from the orbiter and allowed astronauts to walk on the moon, then rejoin the orbiter for the trip home. Note: The Lunar orbiters have all been 1 time use vehicles and the Space Shuttle was never designed as a lunar orbiter, but as an Earth Orbiter, a freight truck between earth surface and low earth orbit.
Currently, there are several active space probes operating around Mars. These include NASA's Perseverance rover, InSight lander, MAVEN orbiter, and Curiosity rover, as well as the ESA's Trace Gas Orbiter.
