E.g. TikTok star is awfully cruel, not primarily fine (10)

I believe the answer is:

influencer

I'm a little stuck... Click here to teach me more about this clue!

'e g tiktok star' is the definition.
I can't judge whether this defines the answer.

'awfully cruel not primarily fine' is the wordplay.
'awfully' indicates an anagram.
'primarily' says to take the initial letters.
The first letter of 'not' is 'n'.
'cruel'+'n'+'fine'='cruelnfine'
'cruelnfine' anagrammed gives 'INFLUENCER'.

'is' is the link.

Can you help me to learn more?
