I tried to find official intel page about this but i couldn't.
Can someone point me towards Intel manuals or tell me here - if there is no difference between logical core 0 and logical core 1 since they both point to 1 physical core and there is no priority of one core over the other?

In the context of current Intel CPUs Hyper-Threading only applies to P-cores as E-cores do not support Hyper-Threading.
According to this Intel web page What is Hyper-Threading? it means that "...the CPU exposes two execution contexts per physical core. This means that one physical core now works like two 'logical cores' that can handle different software threads...". Which suggests no difference between logical cores 0 and 1. Hyper-Threading for P-cores is normally active by default, it can be turned off globally in the BIOS or varied on a per core basis in Windows.
