No. Expertise isn’t a synonym for ‘infallible’ it denotes someone whose lived experience, learned knowledge and skill means that you should listen to their opinion in their area of expertise - and defer to it, unless you have direct and evidence-based reasons for thinking they are wrong.

By that definition an expert would be <more> trustworthy. (Usually they want you to look at credentials instead.)

However that still ignores human nature to use that trust for personal gain.

Nothing about expertise makes someone a saint.
