can you be banned for being constantly bad at a role?

the role im refering to is SUPPORT i do great in other roles but when i support i constatnly do bad i had a master elo draven with mastery 7 vs a gold sup and unranked adc and i could not get the draven fed instead the other adc gets fed this game was about a month ago

in short i absolutely suck with supporting i have like a 90% loss rate at that role am i in danger of being banned with a 90% loss rate at support?
