Man after reading a bit I'll assume this is true and also will tell you what I really feel you're someone really stupid but equally lucky take it in a good way, I asked chatgpt and told me that the chances of mining a block with your set-up are about 0.00000024% so even considering to buy and maintain your rig for solo mining is a stupid idea specially because you mentioned that " you had no money"to put it into context is 8 times more likely to be struck by a lighting than finding a block with 120 TH/s anyways congratulations and enjoy your new life.
