I have googled a lot and i don't seem to find anywhere what that is, does is make any greater differences?

Amiibos are little figurines Nintendo made that unlock bonus content / itemdrops etc. in almost every modern Nintendo console game. You can read more about it on Wikipedia: https://en.wikipedia.org/wiki/Amiibo

For BotW, Amiibos supply you with different items. The Adult Link Amiibo actually gives you Epona.

I don't know what you googled, but when I googled "Amiibo" I got exactly what you wanted to know. http://prntscr.com/ik4afo

Thank you for reviving a 2 month old thread that was already answered to let us know you’re good at Google.

You're welcome. I try.

please don't feed the trolls
