The 1.03 ma looks correct if you have the meter in series. No drain.
The 10.24V looks like you are not measure properly. I don't know where the meter leads are attached. Should be touching the battery posts
Your first pic is confusing. You have the positive (red) DVM lead connected to the negative battery lead. I assume the black lead is on the negative battery post. This setup would degrade the battery voltage by any load your system has including your problem. If all your systems are off, I would think you should read zero volts as the battery should be disconnected from your electrical system. Anything like the radio memory or clock should not drop that much voltage.
I had this problem which was caused by a leaking diode pack in the alternator. Do you know how to check the alternator?
This whole process has made me come to realize that my battery is no good. I just finished re-charging the battery and it only reads 10.5 V across the posts.
The first photo shows Less than 12 V because I have a bad battery. The multimeter is measuring in series with the negative battery terminal and the disconnected negative battery cable.
