How do gloves protect?

I really don't see how wearing gloves helps to protect against viruses like coronavirus. I've read all the comments by those who wear them for this reason, but still don't get it.

Surely, while you are wearing them, the gloves pick up and transfer any viruses you might touch in just the same way as your hands, meaning that the risk of transferring these to your face, purse, phone, bank card, keys etc. is exactly the same as if you had bare hands?

I am ready to change my opinion if people can give me good enough reasons, but so far I haven't come across any convincing arguments or proof.
