Question regarding font usage from Adobe fonts

I have a question regarding fonts activated through our paid subscription to Adobe Creative Cloud. Are there any limitations to usage? We have been using Avant Garde both in our epubs and on our website, however the fonts were purchased directly from foundary Monotype several years ago, which we just discovered come at a cost. We'd like to switch over to the Avant Garde offered by ACC. Are we free to do that and at no additional cost? What is the difference between the two?
