LB – sure!
I was assuming that when you wrote “working in a Kollel” you meant a Rosh Kollel. Is that what you meant?
If you meant being a secretary in a Kollel (or something similar) that would be different. It would definitely be a big Mitzvah and a big zchus, but no one would refer to it as “learning”. Obviously, none of this has anything to do with an individual’s schar in Olam haba which is something that none of us knows and is based on how well one fulfills his own individual tafkid in life. I am simply talking about the terminology “learning” and how the term is used. My point is not to “grade” people. Only Hashem can do that.
