As suggested, bio filtration converts ammonia to nitrites then nitrites to nitrates… adding more fish means adding more ammonia… adding more ammonia results in increasing nitrates at the end of the nitrogen cycle…
So you should expect X ppm of nitrates to result from each fish Oscar added to your hypothetical tank/situation presented above…
Most excessively stocked tanks that last for any amount of time are bare bottomed tanks with little to do décor for waste to collect around. Thorough cleanings and frequent heavy water changes are a must as well as frequently cleaning filters to prevent collected waste from breaking down and contributing to higher nitrates.
All in all these types of tanks have a much higher demand of maintenance and give far less room for error. Also tightly packed fish are more likely to be stressed and therefore more susceptible to disease/infection when something does go wrong.
