The number of nodes in the final .msh file depends on the Physical group definitions. (What is reported in the Statistics window is the raw number of nodes.)

I don't see any gaps in your mesh; beware that the surfaces of the interior sphere are not oriented in a coherent way, which could lead to problems in a BEM code.
(The mesh of the outer shell is also quite strange.)
