Suspended cards don't show up in stats

Hi, I was wondering why suspended cards don’t show up in stats, I’ve got multiple decks that I’m not learning but just “navigating”, answering to cards but I don’t want to add them to the learning cycle. I’m noticing that suspending them (after the right answer) it’s not making them showing in the statistics, as regular cards. There’s something I could do to fix this? I’ve answered to hundreds of cards in this way and they just didn’t leave a trace anywhere in the app. I’m using Anki Desktop for Ubuntu. Thank you on advance.

Which statistics do you mean?
