wtf is this DSA SHite, How to actually do this clusterF*ck thing ???

I have graduated and like am in limbo in a company, they might not renew i have solved only about 176 question on lc , this company was more about apti, projects and core, so i focused on that only. The thing is i did not get this dsa thing in college itself. like what am i supposed to learn patterns to problems and then just apply them or like am i supposed to train my brain on pure logic so that i have about an 85 to 90 probablity to solve these questions. I know java backend so thats it yeah, but like getting this dsa shit right would be great man. Help me out here....
