Will the "Change Owner" Flow Step Change Account Owner?

Hello!

Background: We recently had Marketo open up the account field level edit access so that we can use Marketo to update fields on the SFDC Account object.

Goal: We want to run a clean up campaign to change the lead/contact owner from former employees to current ones.

Question: Since we have the account level edit open, will the "change owner" flow step change account owner as well? If so, how do we make sure we ONLY change lead/contact owner.

Thanks, everyone!
