Will all ps4 games work on ps5?

I have a question and the following example.

Fortunately, I have a PlayStation 5 with the disc version. I wanted to buy the game Jump Force, but it costs 70 euro in the Ps5 store, which of course I'm not willing to spend now I wanted to ask whether I can just buy Jump Force for the Ps4 as a disc from the Expert for 20 euro and the disc simply can put in the Ps5 and can play normally. I would be very happy to hear from you. LG

As far as I know it is possible

Yes, just not the following:

DWVR
Afro Samurai 2 Revenge of Kuma Volume One
TT Isle of Man - Ride on the Edge 2
Just Deal With It!
Shadow Complex Remastered
Robinson: The Journey
We Sing
Hitman Go: Definitive Edition
Shadwen
Joe's Diner

Yes it's possible. There are maybe 1% of PS4 games that are not playable on the PS5
