Please show me all these 3rd party games that had sold 2-3 million when PS4 sales were around 7 million.
PS4 was experiencing record software sales when it was still early on. Everything big to small sold decently to fucking amazing. From third party to first party. Nintendo games sell on Nintendo consoles, third parties generally do not. The only third parties that do sell well are the big japanese franchises, because Nintendo handhelds dominate Japan. Everything else will struggle to reach 500k to 1 million.
