Does praying once in Masjid al-Haram count as Qada' for several years of missed prayers?

assalam walaikum, this is a simple question but i'm struggling to find the answer online if someone has missed out on years of salah can they pray qaza in masjid al-haram to catch up? one prayer in the al-haram is apparently equivalent to 100,000 prayers. can that be used to cover someone's years of not praying? or will they still have to pray every individual missed salah as qaza? i'm sorry if this doesn't make sense. i follow the hanafi maddhab by the way so a hanafi perspective would be appreciated. jazakAllah.
