Transmission drain - metal shavings normal?

As the title states, drained the old fluid into an empty container and noticed a lot of small metal shavings in my pan.
2013 Ml350 with 76k miles.
Edit: This is the first transmission fluid change for the ML

unfortunately wasn’t able to drain torque converter. Neither the upper inspection hole nor the bottom hole had the plug line up and I wasnt prepared to drill.
I will have to do another drain refill at 100k and do so every 30k thereafter.

Looks very normal to me, special this is your first time changing it. You will have to rotate the engine to access the torque convertor. Keep rotating, you will eventually see the drain plug. There are also another tool you can buy if you don't want to remove the torque convertor drain plug, it use air to put the remaining fluid in the system. I think that tool will get most of the fluid out.
