Yes, because technicians are certified and trained, and because safety relevant parts are (no matter if first party or after market!) certified and tested. The relevant list in Germany is at https://www.gesetze-im-internet.de/stvzo_2012/__22a.html.

Of course, sometimes there are problems with car parts (e.g. the airbag mass recall), but counterfeit/uncertified parts generally don't end up in cars - vs. in the mobile/electronic industry where this is more routine than absolute exception.
