It's understandable. Back in the old old days, these 😱 were often called emoticons. The reason was that the chat software that people used to automatically replaced ;-) by 😉. The menu was the same and the name of this menu was emoticon.
One of the most famous example of this is MSN Messenger.
This might be true for you, and your experience, but this distinction is by no means universal. The Unicode standard, for example, has an Emoticons block with all those little images that many people call emoji.
From my experience online, starting before the Web, an emoticon is a simple, abstract emotional content marker that's made from ASCII characters, whereas emoji use expanded, international character sets to build up slightly-more representational images. There's a lot of overlap, but emoticons came from the Anglosphere, while emoji came to the English Internet later on from East Asia, hence the distinct term and similarity of the name emoji to kanji.
In my reckoning, emoticons are displayed sideways to the left, and emoji are displayed upright. 😊
