In brief: Different conditions

Children under the age of 16 cannot get ra.
They get juvenile idiopathic arthritis (jia) which is also an autoimmune disease affecting the joints but very different in many respects. Even as older adults, they are adults with jia. Older teenagers can develop rheumatoid factor positive polyarticulatar jia that looks very similar to RA and may develop into a disease that looks similar to ra.

In brief: Not the same disease

Apart from clinical differences, children are rarely ccp antibody positive, fewer are rf positive, they rarely develop rheumatoid nodules.
We now call jra, juvenile idopathic arthritis, or jia. Most of my children have adult forms of spondyloarthritis preesenting at an early age. They have a stronger family hx for arthritis as well, much stronger than adult RA patients have!

In brief: Yes

Ra is definitely possible in a teen and younger, usually known as juvenile ra.
The differences can be in presentation and often in jra the diagnostic blood tests are different. No one knows the cause, but you should see a rheumatologist to be appropriately diagnosed and treated.

Kids don't get rheumatoid arthritis by definition. Rheumatoid arthritis and juvenile idiopathic(rheumatoid) arthritis are different diseases with different features, different levels of whole body (systemic) involvement, and different prognoses. Some of the same medications can be used to treat both. They are different enough that most adult rheumatologists lack sufficient training and experience to best manage JIA/JRA.
