The statement that entropy does not change in all adiabatic processes is incorrect. While adiabatic processes prevent heat transfer, they can still involve entropy generation due to irreversibilities. In the case of adiabatic reversible processes, the entropy of the system remains constant. Therefore, the distinction between reversible and irreversible adiabatic processes is crucial in understanding entropy changes. Overall, not all adiabatic processes maintain constant entropy.

For all adiabatic processes the entropy of the system does not change (speaking in general) Is this statement correct?

That statement is not correct. Entropy can be both transferred with heat and also generated by irreversibilities within the system. Adiabatic processes eliminate the first possibility.
 
In other words, the entropy of the system does not change for an adiabatic reversible process.
