The stuff I read and people I talk to see it a bit different.
They aren't saying Sancho and Håland play the same position as an example.
As
@MarcelsGoat said, through all my life where I've been going to watch Everton and other football it's pretty much always split into four groups by most people.
The generic term is a forward and in that you have different types and styles: traditional centre forward; false-number 9; target man; poacher etc etc.
They're all forwards though. It's like Kenny is a right back, but he's a more traditional full-back whereas TAA is a right back, but more a right wing back.
