Creating folder in file explorer and Uploading same folder on onedrive online

I have created a folder in Onedrive directory in file explorer. However, when i go OneDrive online, i can't see the folder. At first i suspected that the folder is still syncing. But after waiting for 2 days, the folder is still not shown on OneDrive online.

So i use the upload folder feature on OneDrive online.

Now my concern is, will the folder in file explorer and the one i uploaded be sync?
