How to convince mom that I am not ready for a marriage yet?

Hi, I’m 25(f) btw. The reason my mom suddenly started seeing matches is because my grandma fell ill and yk the typical Indian family she’s saying that before she dies she wants to see your marriage. I said that I am not yet ready because , 1. I don’t think I’m mature enough to handle new and additional responsibilities. 2. My career started 2 years ago and with my current pay check I won’t get a sufficient loan to handle wedding expenses. 3. I want to have a growth in my career because once I married kids will happen and to manage the costs in a typical tier 1 city and with the cost of living that’s being increased I need to at-least earn around 60-70k per month to support both my husband and kids financially. I tried putting these in-front of my mother but she’s reluctant and telling me to get married as soon as she found a good groom. She is neither talking to me nor eating anything because I am rejecting the matches she is bringing. Is there any other way to convince her? Any advice please. Thank you.
