> able to take responsibility This is the big difference - seniors will track and resolve a roadblock or issue that they could justifiably ignore, in particular where other people in the organization are being difficult or obstructive, giving incorrect guidance, etc. A junior will just go "We were told it cant be done/will take 5 weeks" whereas a senior will know that's bullshit and escalate it to the right people.
