First thing Azure web jobs and Azure Scheduler are different. As correctly said by Kamran, your system will not be impacted as you are using Azure web jobs.
Also Azure Scheduler already retire on 30th September 2019. https://azure.microsoft.com/en-in/updates/azure-scheduler-will-retire-on-september-30-2019/
