Commitment in Scrum (as part of the planning) was about the promise of a group of people.
(Caveat: The term is not in the Scrum guide in this way anymore)
Commitment in Flow is about the status of a work item.
In flow-based systems, “committed” for a work item means that this work item is being worked on now.
The work item is meant to be neither idling nor pulled back from the workflow until it is released (to the customer to whom it is meant to be of value).
In Scrum, “committed” for a team meant that the team strives to achieve a goal by all means necessary.
The team was meant to work towards this goal and deliver something that enabled the negotiated customer capability.
“Just” a distinction to be aware of in discussions about commitment...
