Is 2000 ELO hard?

I'm curious, is achieving a rating of 2000 ELO in chess considered a significant challenge for players? For those who are unfamiliar with the ELO rating system, it's a numerical representation of a player's skill level in chess, with higher numbers indicating greater proficiency. So, for those who aspire to reach this milestone, what kind of dedication, practice, and perhaps even natural talent would be required to attain a 2000 ELO rating? Is it something that's achievable for the average player with enough effort, or does it represent a level of mastery that only a select few can hope to attain?
