Windows 10: dodgy coa sticker question

Hello, i have a quite strange dilema. About 2 years ago i bought used dell computer with windows 7 coa sticker on it. it didn't seem much of a stretch it would be actual oryginal sticker that came with the pc, and it activated with no problems even though i had to guess some smeared letters. Than about a year ago that pc died due to water condensation because it lived in very bad conditions so i take coa sticker off and left the husk for recycling after removing every part that i could still use, because only motherboard is ded and i don't like to throw away things i can use in less fortunate pc. Back to the coa sticker though recently i decided to recover cd key from that sticker so i could try to use it in the future perhaps but it was already smeared before and now about 5 signs were unreadable enough to make me guess what they are, so i launched show key plus and begin brure force atempt to guess and i did figured out a cd key that does show up as valid key while containing all reaable letters from my sticker, the problem is i am not sure if it was me randomly guessing a different version of the system , or is that something even bigger. i mean what are the odds for me to type in a partial windows 7 pro oem and fill in the blanks to get windows 7 pro volume licencing key instead? while typing in the blanks i took into consideration how partialy smeared letters look like and that certain alphabet signs like o and 0 do not apear in any coa key so i schould be pretty close to what the oryginal key should be and replacing B with 8, M with H and 6 with G shouldn't give me a different version og licence, it in most cases should give me invalid cd key. i have no idea how those thngs are calculated but i am pretty sure there is no chance for 2 cd kets to have last 16 characters the same (and other 4 from first 2 segments) but being in different licence type just because fews random signs are different. so i have a question Can an windows 7 oem key randomly transform into volume licencing key if you bind it to your computer and microsoft account, or was it always volume licencing key? Or perhaps show key plus downloaded from microsoft store lied to me somehow? I did activated windows 10 pro with this key before and it had no issues with that , i also registered that cd key to my windows account with no problem so i could transfer it to a different pc if i needed to, but now it looks it was a volume licencing key all along. Have any of you seen something similar?
