TL;DR : no (unless you're a cyborg). ok since every one is too lazy to explain in detail and I am bored atm, I am gonna do it . before I start , at the time that I am writing this , to be ranked #50,000 you should have around ~3.285pp, now to put it simple , the overall pp score is calculated in a way that makes your highest pp score worth it's whole value and the other plays worth slightly less that the plays above them; and thus if you want to get ranked at least #50,000 with one play you need that play to be worth at least ~3.285pp which is the equivalent of doing something like "Spawn of Possession -Apparition (https://osu.ppy.sh/b/690982) HD DT HR" with a 85% acc . obviously a normal human can never reach that lever , it's just way beyond human limits (unless you're a hacker or an advanced human from the year 6900). for more information about the pp system here's a useful link that explains it in details https://osu.ppy.sh/help/wiki/Performance_Points I hope that I was useful with thing long (and probably full of english errors xD ) post , GL HF.
In Standard no one has acheived a score that would be worth as much by itself (excluding hackers) of the amount equal to rank 50,000 In Taiko it is possible but you'd need about a ~750PP play which has only been managed by 2 people and would be very difficulty In CTB it would actually be really easy as you'd only need a 360PP play which many many people have managed In Mania you would need a play of around ~1300PP which several top players have managed due to Mania's PP system being insane.
