Also, a climbing rose needs a huge pot to climb properly: 1/4 of the average size of the area you want it to cover. For example, a climber in a 50 cm pot will only cover an area 2 meters by 2 meters.

The first is correct. Ramblers are meant to do just that: ramble. Cutting to the ground will only work for climbers, and bedding roses. The second one may not be a true climber. Many 'climbers' are tall shrubs which can be tied in to a wall or support. Need to know the cultivar for sure.
