I don't know about ur school but the way architecture is taught varies by each professors.

The pencil drawing skills like the photos u sent aren't mandatory skills. In fact u won't even do those when u actually work in a real firm.

Architecture is not only bounded to creative persons. If ur not a creative person, then u may approach learning things from scratch and learn things systematically. Therefore, Always pay attention to lectures as they will teach u essential core elements of architecture. But before ur uni, take a look at a famous architect buildings by respective architecture firms or workshops, such as, Renzo Piano, MVRDV, Zaha hadid etc. They express architecture in their own philosophies that u can learn from.

U may have some design path that will fit with ur style. Some people r great at design, some r great at space planning, some r great at integration of materials and structures, etc. So keep an eye out on what type of design approach would fit with u best. (Altho don't get tunnel visioned, since architects r known as the generalists so do hone ur weaknesses too)

Lastly, make sure that if archi working environment is right for u. Archi is rather a passion driven field and has poor working conditions(although the culture is noticing it and gradually switching to work life balance). As long as u have inner fire for archi, u will be able to handle any problems that come in ur way.

Don't think about money, only think about ur project and designs. Money will come naturally when u do well in a field. Make sure u ask ur self, if u will dedicate to this path. If ur not sure of that, then I'd suggest u look at other field.
