Is it normal that i can climb so well by playing so much champs in the jg?

Or am i just lucky? I mean, im trying to pick accordingly to my allies pick every game, but there is some champs that i barely play and still win with. People say its better to one trick but on my side it looks like i climb so much better playing all the colors of the rainbow depending on team comp. https://na.op.gg/summoner/userName=Le%20Maitre%20Dragon
