I want to disable one finger scrolling with my Magic Mouse while I click with it, because I don't like that it scrolls the content in apps if I click something. I also don't see any practical use of letting this thing enabled.

Very important, that I want to keep the scrolling on, which I generally love, so shrinking the scroll area with MagicPrefs or disabling scrolling fully is not a good workaround for me.
Are there any tools which let me disable any scroll events during the mouse button is down?

Since we've established that your Magic Mouse doesn't have this behaviour with another computer, I'd reset your NVRAM and also do a boot into Safe Mode.
Resetting the NVRAM
Older Macs had what's called Parameter RAM (PRAM), newer Macs use Non-Volatile Random-Access Memory (NVRAM).
Since you haven't specified what model of Mac you're using, below are some generic steps that will work with all models (including all Late-2016 MacBook Pro models):
Now test your Magic Mouse to determine if the issue is still present. If this doesn't resolve it for you, proceed to booting into Safe Mode.
Note 1: When you log back in you may need to readjust some of your system preferences (e.g. speaker volume, screen resolution, startup disk selection, time zone information, etc).
Boot into Safe Mode
Follow these steps to boot your Mac into Safe Mode:
Once you've booted into Safe Mode, let me know how you went and we'll go from there.
Trash Magic Mouse .plist files
Since your issue persists both in and out of Safe Mode, I would trash the relevant Magic Mouse preference files.
As you don't specify what version of macOS you're using, I'll assume you're running a version from Mountain Lion and above. Follow these steps:
Your Mac will now create a new set of default preference files for your Magic Mouse.
Note: You will need to go back to System Preferences and reconfigure your Magic Mouse settings. However, before doing that I would test the Magic Mouse first to see if the problem behaviour still persists.
Reset Bluetooth Device List and Bluetooth Controller
This is something I've had a number of users do to resolve issues with 3rd party Bluetooth devices (usually a keyboard and/or mouse, but also headphones etc).
Since you're using a genuine Apple Magic Mouse you my decide not to bother, but I think it's worth trying.
In a nutshell you need to reset both the macOS Bluetooth Device List and Bluetooth Controller. However, this will reset all connected Bluetooth devices, including your keyboard and mouse, so each Bluetooth device will need to be paired again.
I have some steps you can follow, but I strongly suggest you read all of the steps first before commencing (or perhaps print out the instructions / view them on another device).
Before starting, ensure you have the Bluetooth icon showing in the menu bar. If it is not there, open System Preferences > Bluetooth and enable the option Show Bluetooth in Menu Bar.
Also, since you're trying to resolve an issue with your Magic Mouse, you will need to use another mouse to follow these steps:
Let me know how you go.
