but in about 5 years XBox/Microsoft Gaming have spent near a trillion dollars in videogame stuff (both the massive buyouts of Zenimax and ABK, smaller studios and buying stakes on other videogame-related things).

In all fairness, even with diminishing market viability for Xbox consoles from the 360 days, Microsoft Gaming/Microsoft as a whole has effectively limitless coffers. 

Microsoft as a whole makes insane revenue and profits, in addition to their war chests. Microsoft Gaming is highly profitable as well, thanks to the blurring of lines on PC and Xbox consoles. 

Xbox could get down to 10-20 million units sold of a console during its lifetime and still be able to fund another console because it's Microsoft.

Whilst Microsoft has the resources to "weather multiple storms". - They do actually still have limits.
And those limits are... Shareholders.
If Shareholders don't get a return on investment, then they will divest or shutter the group or parts of it.

Microsoft's saving grace is the PC.
