Is this use of apostrophes correct or not? (1 Viewer)

[PhysicsMaths]

I see it used all the time...
"Mathew's the best"
"Bob's lifting the weights"

Is this a correct use of apostrophes?
I'm pretty sure that for people, apostrophes are used as possessives only

Remember contractions. Mathew is the best, shorten it becomes Mathew's the best

I had no idea that apostrophes contract names as well
