Why don't you just look it up?

Here's Wikipedia

According to the teaching of the First Vatican Council and Catholic tradition, the conditions required for ex cathedra papal teaching are as follows:

• the Roman Pontiff
• speaks ex cathedra,
• that is, when, (in the discharge of his office as shepherd and teacher of all Christians, and by virtue of his supreme apostolic authority,)
• he defines
• a doctrine
• concerning faith or morals
• to be held by the whole Church.

For a teaching by a pope or ecumenical council to be recognized as infallible, the teaching must:

• Be a decision of the supreme teaching authority of the Church (the Pope alone or with the College of Bishops)
• Concern a doctrine of faith or morals
• Bind the universal Church
• Be proposed as something to hold firmly and immutably

Each of those phrases is constitutive for infallibility. If one condition is missing, what you have is a non-infallible statement.

So basically, anything else he says, or any other Catholic leader says, is up for grabs.

A Catholic can take it or leave it as they see fit and have their own personal interpretation of Catholicism.
