You're pretty much spot on. My average game length is 5 minutes and 7 seconds. lichess tells me my time spent playing is 54 days, 5 hours and 6 minutes and now 15,273 games.
It works out to average just under an hour a day, and I play most days.
Breakdown: 6,157 bullet (90+% are 1+0 but a few 2+1) 7,430 blitz (90+% are 5+0 but a few 3+2) 1,368 rapid (99+% are 10+0) 184 classical (100% are 30+0)
I've also played a small handful of correspondence, chess960, etc. which is why it doesn't quite add up.
