Is it advisable to create partitions for 1 TB SSD of macbook pro i9

As has already been said, there is no reason to partition (except possibly for bootcamp).

APFS lets you create volumes in the same container without partitioning.

These are much better than partitions, because they automatically share the available space, and you never fall into the situation where you suddenly run out of space in one partition and have plenty in another.

It is as simple as "Add APFS Volume" in Disk Utility.

As others said. No reasons to do that.

In the past, you would partition large disks for manageability. Segregate what change often (ex: Data) from what rarely change (ex: OS, applications...). Optimize disk usage and overcome file system limitations...

Nowadays, on consumer devices and modern file systems there is no reason to create "partitions".

Create partitions for what reason?

I can think of no good reason to do it,

Just to add, the only partition I can imagine creating is a Boot Camp partition if you're planning on installing Windows.
