You won't receive confirmation in the coming days, unless you try to use the transaction accelerator linked above. It's really straightforward to use, just make sure you try to accelerate it every full hour, when in the first few seconds there are 100 free slots to take (and there are really a lot of people who wait for that first few seconds to accelerate their own 'low cost' transaction).
Your transaction has 79 sat/B fee, but as of now, the average transaction fee is 10 times more, over 700 sat/B, this is why I say that it makes no sense just to wait for the confirmations....

It clearly says that the sender has sent you an unspent input which in this case means that he has sent you the BTC which has not been confirmed yet on his address. Once the coins are confirmed on his address they will be transferred to your address. This might take a while seeing the coongested BTC network and all you can do is wait until you receive the coins.
So this means that the sender has got his coins in his wallet and now the coins will be sent to your wallet according to fees paid. The current network fees is too high and it might take some more time for your wallet to get credited with the BTC.
Post the transaction ID for further clarificaitons.

Welcome to this forum as your are newbie still it will take some time to understand things.

Anyways, Bitcoin is share or token system which is decentralized, but to give more security and transparency to transaction it needs to verify by miner and keep this ledger record open for every node to re-verify.

Whatever amount you have bought is received to wallet address from senders wallet address. So in such transaction remaining amount is stored to sender address with unspent. for these transaction it require fees, and this fees paid to miner to verify broadcasted transaction.

Generally its take 8 to 9 minutes to solve 1 block, so always check in which block your transaction included. So that you can check wheather this block get solved or not and who relayed it.
