While the vast majority of current cases are preventable (and in most cases, reversible) through proper lifestyle changes, between 5% and 10% of people with T2DM were going to develop it regardless of what they did. Now, it's possible that some or all of those cases are not actually T2DM. In the past few decades researchers have been investigating additional forms of DM, such as Latent Autoimmune Diabetes in Adults, that may be the cause of some cases of DM that currently present as T2DM. It may be that once "true" T2DM is defined that your statement is correct, but as of right now it is not.
