GMs & IMs I'm looking for a simplified explanation of how does an individual gain both the status of a Grandmaster and an International Grandmaster and also a brief overview of the ELO rating system. I would appreciate any feedback on both topics. Thanks!!

From the FIDE handbook Requirements for the titles designated in 0.31:

The working of the FIDE Rating System:

Rating system math is always complicated, but the gist is that the difference in two players' ratings should accurately describe the expected outcome of a game between the two players; the larger the rating difference, the more likely it is that the higher-rated player will win. So to account for this, if the higher-rated player wins, he will gain fewer points (and the lower-rated player will lose fewer points) than if the lower-rated player had won (and accordingly, if the lower-rated player wins, the higher-rated player loses more points as well).
