This has been said to death but it's nigh impossible for a system released years later to have a big impact on existing consoles. I don't get why so much struggle about something so simple. Of course the switch competes with the ps4 and xb1 (and later ps5 and xsx for a while).

The numbers show it didn't directly compete with PS4/Xbone, so why would it compete with its successors which will be basically the same?

The numbers are what they are and the switch competes directly with the other systems. If they are on the market at the same time, they are competing.
