Not at all.
For a beginner, it can sometimes be a little more challenging to start with a quad - which I personally have not experienced.
If you watch all the excellent video tutorials by John Barresi (https://kitelife.com/video-tutorials/) or the videos by Joe Hadzicki (https://www.youtube.com/channel/UCPGoYYsZNoOIHIjpdTNkKgQ), then you already have a good basis for the start. It is even better if you have a quad pilot nearby who will take you along, teach you and let you fly a few different kites.
For your first quad, a used one is always recommended for practice. Most used kites do not come with a line or handles (only the sail).
For lines we recommend for the beginning: approx. 25 meter 90 lb (1kg = 0.5 lb = 1kp = 0,981daN)
Handles gladly also used - but with knot ladder.
For the sail it is important that you choose it according to your prevailing wind conditions/range. A sail can have different ventilations: SUL for little wind, Semi Vented for light wind with sudden gusts or XT for very much & constant wind at the coast.
