Stars don't have a set pattern. They do travel across the space, although from our point of view it takes very long for them to change position on the heaven sphere.
Constellations won't look the same forever.
Also note that stars in the same constellations don't neccesarily have to be close together. Often their relative distances are greatly larger than their distances to us.
There was no set pattern for stars on the US flag and the individual who proposed the flag, Francis Hopkinson, did not set them in a circle but in the pattern of the crosses on the flag of Great Britain. Thus they were scattered.
A pattern of stars in the sky is called a Constellation!(: The name for a pattern of stars is an Asterism, of which the named Constellations are some but not all.
The word for stars that do make a pattern is "asterism" (not constellation; that's actually defined differently). There isn't really a word for a group of stars that don't make a pattern, because there's no such thing: any arbitrarily chosen group of stars will make a pattern, even if that pattern is essentially random.

A pattern of stars is a grouping of stars perceived as a figure or design: Orion, The big Dipper, are two examples.
Those are called "circumpular" stars. Exactly which stars are circumpolar depends on your location. For example, if you live 30° south of the equator, all stars that are up to 30° from the south pole of the sky will never set.
When stars are organized in a visible pattern they are normally referred to as constellations. Examples of constellations include Orion, Capricorn and Taurus.
