Re: Small gap between upper and lower joint

If it was a 0.1-0.2mm difference between the diameter of the tenon and the socket, then that will be an entirely different matter.

A tenon that's around 0.1-0.2mm longer than the socket isn't anything to worry about. yes they could probably be machined to fit better, but a guaranteed gap-free fit between the upper and lower joint bores is ensured with a fractionally longer tenon.

Fairly often the socket ring is slightly proud of the socket either due to machining of the socket ring slot or the extra thickness of the socket ring after being plated, so that can prevent the joints fitting perfectly together.

Absolute text book accuracy isn't ever likely achieved in any woodwind instrument. You can get very close, but never absolutely dead perfect. Remember that wood is a live material and metal is unforgiving, so neither materials are suited to being used together.
