In any case, to compete with a business you don't have to do everything
that that business does or do it in the same way. The few remaining
bookshops, for example, are in competition with Amazon, despite not
also selling beer and sex toys, despite not stocking many books, and
despite not delivering them to your door for free.
Which is why people can easily set up competitors for Uber by
cherry-picking a bit of its market (just one of the types of service,
one city, etc).

Why does cherry-picking a bit of Uber's market count as competing with
Uber but cherry-picking a bit of Amazon's market doesn't count as
competing with Amazon?

In the sense you ask, because the only product being cherry picked from
Uber is transport *here*, whereas the thing which isn't in fact being
cherry picked from Amazon is mail ordering a specialist product.
