I wouldn't say there is no risk. The absolute number one biggest risk is uneducated and/or irresponsible owners. There are tons and tons of things the owner can do wrong that would put a flighted parrot at high risk (the majority of these things apply to clipped parrots as well to an extent). Some things would only apply to flighted parrots (like leaving a ceiling fan on). One problem is that a flighted parrot has more opportunities to get into trouble more quickly. So let's say the owner left out toxic foods, plants, electrical wires, etc and isn't adequately supervising. It's not impossible that a clipped parrot get into these but the flighted parrot may be able to get into more trouble more quickly.
Now with proper precautions, bird proofing, educated owners, and a bird friendly environment, I would say the flight risks are quite small. The biggest one I can think of is getting caught trying to fly through a door someone is closing. You just gotta realize this and be careful. Now in terms of flying into windows, mirrors, and walls the risk is negligible when the bird is raised around this. Yes it will crash into them a few times while it is learning to fly but if done young it does not do damage and they learn this well for life.

Well this is because most people still have not figured out how to keep them and are looking for that talking, colorful, hamster thing. Just because people keep doing it doesn't mean it's good for the bird or the relationship. I would not buy from any breeder that is insistent on clipping. On the other hand, I'd be hard pressed if not impossible to find a breeder that never does.

Depends on some factors but usually 9-18 months after weening. It takes a while. Especially for the entire molt to complete and replace all feathers. If the feathers grow in properly they should be as good if not better (babies may have some stress bars and imperfections). However, there is risk that new feathers will not grow in properly after a clip. Kili would grow one feather back in at a time and as it was unprotected, it would get broken. Then the next would have the same problem, etc. Because of this she is still missing some flight feathers several years later. I would not clip a parrot at all for this reason among many others.

Does it entirely prevent a safe flight or would ti make the action more difficult thereby limiting long distance flight potential.
Clipping fewer feathers would make it harder for the parrot to fly in varying degrees. This may sound like a good idea but it isn't. What are you trying to achieve? The purpose most people clip parrots is to punish them for flying. Whenever the parrot tries to fly, it can't, falls down, gets hurt. This teaches it not to even try to fly. Furthermore the wings atrophy. So people who've had parrots clipped for many years will brag that they don't even clip the wings and the bird never tries to fly. Well this is because it was psychologically and physically broken from being able to so that's how it goes about. I think it is good for a young breeder raised bird to just have full flight and explore. Let it crash a few times and learn to use its wings. These skills will be useful later in life.
Probably the worst clip is the one that is on the boundary of flighted and not. The bird probably gets really confused because it tries to fly and sort of can but can't. It will overwork itself trying to fly to where it wants but may misjudge the distance and end up landing short or crashing. For instance the bird wants to land on a counter but loses too much height and smacks into the cabinets below.
If your household, lifestyle, or preference does not support a flighted parrot filled with energy, enthusiasm, and crazy ideas about what to do for fun, I would strongly urge you not to get a parrot. Not trying to be mean, not saying you wouldn't have good things in mind, just speaking from personal experience with flighted/unflighted parrots and from a bit of understanding of avian physiology and psychology.
