If you mean Jiu-Jitsu as in Brazilian Jiu-Jitsu then yes, there is a big difference. But if you mean jiu Jitsu as in Japanese Jujutsu, then no, there isn't much of a difference.
Small circle Jujutsu is a variation off of traditional Japanese Jujutsu. Where Brazilian Jiu-Jitsu is a variation off of Judo, which is specialized from traditional Japanese Jujutsu.
Also, traditional Japanese Jujutsu and Small Circle are 90-95% standing up and involve very little ground work, whereas Brazilian Jiu-Jitsu is the opposite, being 90-95% ground work.
A great circle lies in the plane that includes the center of the Earth. The plane of a small circle doesn't include the center of the Earth.
A small circle is a simple circle on a two dimensional plane. The great circle is the circle around a sphere that is on the plane that intersects with the center of the sphere. It is the reason that on a flat map the paths of planes seem to curve to go to and from Europe and the North American continent.

A great circle is a circle on the surface of a sphere that has the same center as the sphere, while a small circle does not share the same center as the sphere. Great circles have the largest circumference of all circles on a sphere, whereas small circles have smaller circumferences. The equator is an example of a great circle on Earth, while lines of latitude other than the equator are examples of small circles.
The difference is that a change forms.

small is just small. tiny is very very small.
Tycho was the first astronomer to make measurements of enough accuracy to show that the older theories were producing errors in the planets' positions. The difference between an ellipse and the old model of a circle and epicycle, which gives a circle with the Sun off-centre, was so small that it needed high accuracy to notice the difference. Planets' orbits have an extremely small difference between the major and minor axes of the ellipses.

Effectively, the answer is that a regular polygon could have an infinite number of sides. However, when the number of sides reaches a thousand or so there is very little difference to the naked eye between such a polygon and a circle. For information : Some of the early calculations for pi were based on the very small difference between a polygon with a very large number of sides and a circle.
