That’s just how player counts work, and why concurrent numbers are problematic to read too much into. Read Dead Redemption 2 has a peak player count on Steam of 99,993 and its estimated to have sold over 20m+ copies on Steam. Games that sell a lot over time do not have big concurrent numbers.
If you sell something like 5k copies a day, then that’s almost 2m a year. Live service games remain in the public eye constantly and instead of falling 2000 in the sales charts they tend to remain around 100-200 and those sales add up over time. Sea of Thieves sold 1m in its first month available on Steam btw.
