Am I basically fired?

Am I basically fired?

I was put on a PIP a month ago, I work as a cloud engineer for some context and from Toronto. I basically got a first written warning which was performance related and that was quite an eye opener for me. I started working more harder and closing my projects on time. 2 days ago i had another meeting with the higher up’s and was grilled again on some mistakes made on the projects that closed up. I did highlight to them that I did put in the work and wanted to show the team that I could be an asset. That however followed up with a second written warning and I felt it to be a bit unfair even if I made some mistakes. I am just wondering is there even a point of thinking I will be safe if I kept working hard or this is just formal steps to dismiss me soon? I really need some guidance on this as I have already started looking for jobs.
