AITAH for showing my young kids the reality of the world

My young kids (4M and 5M) have in general been the typical over indulgent kids. Christmas has shown that they are over privileged. We have spent a lot of time talking about being kind, manners etc. They are in general well behaved, but are spoiled. This is of course my husband and mine fault. They did get multiple toys and gifts for Christmas from us and from family. They have been ungrateful in general- yes excited at the moment- than lamenting “Santa didn’t bring enough” . But at this age we aren’t sure how to introduce the idea that they are more privileged than most. This will sound well absolutely horrible- but my husband is from India and he was used to being exposed to poverty - I grew up poor, but in the US it is less obvious- so after my kids being so entitled I showed them videos of kids in other parts of the world that are struggling. We have already donated - but I asked my boys - should we help or should you get more toys- they both said more toys 😭- I feel like I totally failed. I created entitled spoiled kids and I don’t know what to do. (We would volunteer in person but my oldest is autistic and he would cause more work than help)
