Bitcoin is verifiable but to be able to do it a special knowledge is needed. So yes we put trust in those who have that knowledge because we are unable to do it ourselves. And there are ways to reduce the risk when couple different _independent_ verifiers do their work properly. Also the system needs to be kept as simple as possible to be secure. For example spammers, scammers, shitcoiners VCs that want to add complexity to Bitcoin is an attack on Bitcoin security, not just a spam that abuses Bitcoin's nodes and network.
