What's your point here? That the Nazis wasted a lot of combat potential in favour of genocide? If that is your point, then bravo! You've reached a level of understanding not often seen by deniers.
Actually the Nazis were fairly efficient in how they assigned such manpower, since by the time they needed more concentration camp guards they had quite a few wounded Waffen-SS veterans to reassign, and also used collaborator manpower extensively at the Reinhard camps.
Mobile units like the police battalions and Einsatzgruppen were fairly time-efficient, since they were flexibly tasked to general occupation service or antipartisan warfare and in the case of police battalions, also committed at the front, while also carrying out genocidal assignments.
Police Battalion 310 for example spent the first years of the war on pure occupation duties in Poland, then was moved to Galicia where it helped shoot Soviet commissars, then was sent to the Leningrad front for months on end, was pulled out, and sent to Volhynia, whereupon it massacred multiple Belorussian villages while also providing the lion's share of the shooters for the mass murder of nearly 50,000 Jews, including the whole of the rather large Pinsk ghetto, in autumn 1942. When the Axis front collapsed on the Don after the Stalingrad encirclement, it was sent along with other units from its regiment to the Don bend, where it was destroyed in frontline combat. Thus, the 500 or so men of Police Battalion 310 contributed just under 1% of the genocide of the Jews, and did so in the space of a few months.
Providing security troops for the occupied territories and for guarding prisoner of war camps drained a significant amount of Nazi manpower, vastly more than was used in carrying out the Holocaust, but this manpower was typically much older and less suited for frontline infantry combat. Nonetheless, in a pinch, police units and Army security battalions were committed to plug gaps, despite high losses and poor combat performance compared to regular infantry divisions.
There were certainly a lot of guards overseeing POWs, foreign labourers and KZ prisoners in Germany, but the size of the KZ system only became really significant in the final year of the war, by which time occupied territories had been lost, and the retreating security units were invariably reassigned if they had not been destroyed in combat. The age profile of KZ guards was fairly middle-aged or elderly, sprinkled with numerous wounded Waffen-SS veterans who were no longer of use at the front, so even though there were 37,000 concentration camp guards by January 1945, you could not have formed a useful division out of them - not least because they lacked the heavy weapons needed to fight any of the Allies by this stage in the war. And nearly 4,000 of the camp guards were women.
The ultimate problem faced by the Nazis was simply imperial overstretch; not having enough manpower to generate forces to serve on all the many fronts across the length and breadth of Europe. That is of course why they lost the war, and that has essentially nothing to do with the Holocaust.
