Hello student no that's not true taking a stream at class 11 level and comparing with direct unemployment is two different things competition is everywhere you need to work hard face lots of examination and huddles to get a good job in  every stream yes it's true that if you choose science stream you've little extra options available after class 12 than commerce but that doesn't mean you should choose science. You should choose stream very wisely in which you're really interested in Which your want to build your career.

Feel free to comment if you have any doubt

Good luck
