you can get into anything remotely quantitative with a math degree, especially if your uni isn't meme-tier and forced you to sit through some programming classes. With just a BS, you have access to quant jobs in finance, or meme "analytics" jobs, or even steal straight programming jobs from CS grads if you took extra programming courses on the side. If you're willing to get accreditation and go through exams, you can even try your hand at actuarial science.
If you're more interested in research or pretty much anything that requires an MS or PhD, math is pretty much the gateway to any field. For example, it's rare to find researchers who got a BS biology move out of the wet lab, because they're more or less digitally and mathematically illiterate. However, if you have a math degree and apply for a bio grad program, you can research more interesting fields such as biostatistics or bioinformatics, instead of being a lowly pipette bitch. Besides natural science, other fields you could get into with a math degree plus grad school include operations research and data science (aka applied statistics).
Basically, by not being a complete mathlet, you pretty much get a leg up in starting your career.
