It means that too many people are downloading the file for it to be available again in the next 24 hours. You can get around it by doing the following:
1. Make sure your logged in to Google Drive
2. Find the file that you want to download and right click it
3. Select "Add to Starred" from the drop down
4. Go to your drive and select "Starred" from the folders on the left side of the screen
5. Choose the file you want to download and right click it again
6. Select "Make a copy" from the drop down
You should now be able to download the file normally. However, I persoally like to download the file like an external downloadable link. You can do this by double clicking the file which should open the file preview. Then you should click the menu button on the upper right hand corner and select open in new window. Finally, you can hit download and it should pop open on another tab as a downloadable link. I don't know if this actually makes any difference to download speeds or anything, but these steps were recommended to me by a friend specifically for downloading large files from google drive.
Edit 1: If it is taking too long to make copies, log out and then try logging back in while using a VPN like NordVPN or Opera browsers integrated VPN and then try making the copies again. If you are using a VPN with slow download speeds or a limited data usage, then after making the copies, log out of drive again, turn off vpns, and then log back in and download the files.
Edit 2: Making copies of large files will take up a large amount of storage on drive. Delete the copies after downloading them so you have more space to make more copies.
