I did a master’s in mathematics and am now doing a course for SAP FICO. Is it really tough for me to get a job or learn SAP Fico as a non-commerce student?

Not really a big disadvantage but though Finance background does help a bit in your early career as SAP FICO consultant.

You can still start from scratch and with hands on experience and continuous learning you should be able to come up to speed soon.
