Oh yeah club hockey has been around a long time and Auburn has had a few teams at different times dating back to the 80s at least.
College club hockey in general though isn't the easiest to follow or have very accurate rankings due to the leagues and divisions. This was a division 2 club tournament, but not ACHA division 2, which traditionally has been where the better club teams participate.
For reference, some of the recent schools to make the jump from club to NCAA D1 (like Lindenwood and Penn St) dominated ACHA D1 for multiple years.
