mounting/change permission of partition

I set up a partition/ext4 of a nvme. Even though it shows as mounted, i dont think its actually mounted. I have Code:sudo mount /dev/nvme1n1p1 /mnt/data] and i check Code: lsblk -f and it shows as mounted. Whatever files i write to in /mnt/data it remains whether or not the m.2 is mounted or not.

I also tired to change permissions to the partition with Code:sudo chmod 777 /dev/disk/by-uuid/e9a483d3-2923-4e48-818c-4738a9151414 , but it doesnt work. i still have to sudo my cmds.

thanks in advance.
