Un billet ou un ticket

In audio lesson 3.3 the word 'un ticket' is used. However, previous lessons used the word 'un billet'. Is there a difference between these words, or is lesson 3.3 just using an anglisied word? instead of the traditional french word.

In modern French it is quite common to use un ticket, even though there is a strong movement in France to keep the language free from anglizisms. However you can't use the word "ticket" in all situations where you would say ticket in English. For example a parking ticket is not a ticket but "une contravention"
