am i considered jewish & how to engage in judaism more?

hi there, i found out when i was about 12 that my grandma on my mum’s side is jewish therefore making my mum jewish too. i’ve always been slightly confused whether i too would be considered jewish or not since my dad is catholic & i was actually baptised when i was younger in the catholic church and my mum has never really introduced me to anything jewish like going to synagogue etc. despite this, would i still be considered jewish and if so, how can i start engaging in the religion & finding out more about what it means to be jewish? any help is appreciated 🙂
