Bronze/Gold Elo ~ Any Big differences?

Hi, Is there a big skill gap between bronze and gold, and how about silver and gold?

ive been trying to get to gold the last 3 days, i always Win, lose, Win, Lose.

so i took a day off. and went ham, got around 12 win streak and finaly reached gold V. now i'm wondering if there is a gap in skill between bronze/silver vs gold ?

i'm climbing so far, so i'm not sure where i'll stand. Tell me what you think of those 3 ranks, thanks.
